Abstract

The aim of the present study was to evaluate the impact of biofield energy treatment on the thermal, spectroscopic, and chemical properties of benzophenone. The study was done using various analytical methods such as gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography (HPLC), differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-Vis) spectroscopy. The benzophenone sample was divided into two parts, one part was subjected to Mr. Trivedi’s biofield energy treatment, called as treated and the other part was remained as untreated, called as control. Mass spectra showed the molecular ion peak at m/z = 182 in control and all the treated benzophenone samples with different intensities (treated samples further divided in to three parts, T1, T2, and T3 for GC-MS study). The isotopic abundance ratio of 2H/1H, 13C/12C (PM+1)/PM and in treated sample was decreased by 44.87% in T2 and slightly increased upto 5.79% in case of T1 as compared to the control [where, PM- primary molecule, (PM+1)- isotopic molecule either for 13C or 2H]. Moreover, isotopic abundance ratio of 18O/16O (PM+2)/PM in the treated sample was increased up to 22.64% in T3. The retention time of treated benzophenone was slightly increased (0.88 min) as compared to the control in HPLC chromatogram. The DSC data exhibited that the heat of degradation of treated benzophenone was increased by 674.16% as compared to the control. While, C=O stretching frequency of treated sample was shifted by 6 cm-1 to low energy region in FT-IR spectroscopy. Further, the UV-Vis spectra of control sample showed characteristic absorption peaks at 210 nm and 257 nm that was blue shifted to 205 nm and 252 nm, respectively in the treated sample. These results suggested that biofield treatment has significantly altered the thermal, spectroscopic, and chemical properties of benzophenone, which could make them more useful as reaction intermediate in industrial applications.

1. Introduction

Benzophenone is an aromatic ketone, generally used in cosmetic products as ultraviolet (UV) absorber however it is suspected of causing cancer and toxic to aquatic life with long-term effects [1]. The UV absorption arises from the conjugation of the electrons between the two benzene rings and the carbonyl C=O group (Figure 1) [2].

The chemicals that absorb UV radiation in the range of 280-400 nm are called UV filter molecules. These chemicals are added to sunscreen products such as lipsticks, lotions, fragrances, skin lotions, hair sprays and shampoos in concentration upto 10% [3]. Apart from their advantageous properties, some UV-filters interfere with the endocrine system of mammals leading to adverse effects on reproduction and development [4]. Moreover, benzophenone can be used as a photo initiator in UV-curing applications [5], this can also be used as UV filter in plastic packaging material to prevent photo-degradation of the packaged content. The use of benzophenone allows manufacturers to package the products in clear glass or plastic without which, opaque or dark packaging would be required [6]. Further, the insecticidal activities of benzophenone hydrazones were first described by researchers at DuPont in 1973. Subsequently,Copping and coworkers reported type I substituted hydrazones for the first time, which showed exciting insecticidal activity against lepidopteron and other insect pests [7]. Benzophenone is used as flavor ingredient, a fragrance enhancer, a perfume fixative, and an additive for plastics coating and adhesive formulations. It is also used in the manufacture of insecticides, agricultural chemicals hypnotic drugs, antihistamines and other pharmaceuticals [8].

Besides its high usability as industrial chemical, it contributes to carcinogenicity due to the high reactivity and instability of benzophenone anion (benzophenone work via formation of an anion). Hence, the stability of benzophenone is important to perform controlled reduction at normal reaction conditions, which could be enhanced by Mr. Trivedi’s unique biofield energy treatment, which is already known to alter the physical and structural properties of various living organisms and non-living substances [9]. The biofield is the energy fields that purportedly surround and penetrate the human body. Human has the ability to harness this form of energy from the universe and can transmit into any object around the Globe. The object(s) always receive the energy and responded into useful way. This process is known as biofield treatment. Mr. Trivedi’s unique biofield treatment is also called as The Trivedi Effect®. The impact of the Trivedi Effect has been well studied in various research fields like microbiology [9, 10], materials sciences [11, 12], and agricultural research [13]. Based on the outstanding results achieved by biofield treatment on microbiology, materials sciences, and in agricultural research, an attempt was made to evaluate the effect of biofield treatment on thermal, spectroscopic and chemical properties with special interest of change in isotopic abundance ratio, (PM+1)/PM and (PM+2)/PM in benzophenone.

2. Experimental

Benzophenone was procured from Research Lab., India. The compound was distributed into two groups, where one part was referred as control and the other as treated group. The treated group in sealed pack was handed over to Mr. Trivedi for biofield treatment through his energy transmission process under standard laboratory conditions. The control and treated samples were characterized using, gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography (HPLC), differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-Vis) spectroscopy.

2.1. GC-MS

The gas chromatography-mass spectroscopy (GC-MS) analysis was performed on Perkin Elmer/auto system XL with Turbo mass, USA, having detection limit up to 1 picogram. For GC-MS analysis the treated sample was further divided into three parts as T1, T2, and T3. The GC-MS spectra were plotted as the % abundance vs. mass to charge ratio (m/z). The isotopic abundance ratio 13C/12C or 2H/1H, (PM+1)/PM, and 18O/16O, (PM+2)/PM was expressed by its deviation in treated samples as compared to the control. The percentage change in isotopic ratio (PM+1)/PM and (PM+2)/PM were calculated on a percentage scale from the following formula:

For-1

Where, RTreated and RControl are the ratio of intensity at (PM+1) to PM in mass spectra of treated and control samples, respectively.

2.2. HPLC

The HPLC analysis was performed on a Knauer High Performance Liquid Chromatograph (Berlin, Germany), equipped with Smartline Pump 1000 and a UV 2600 detector. Chromatographic separation was performed on a C18 column (Eurospher 100) with a dimension of 250 × 4 mm and 5 μm particle size. The mobile phase used was methanol with a flow rate of 1 mL/min. Temperature of the experiment was kept ~25°C. The solutions of standard and the samples were prepared in methanol. The method development for this assay of benzophenone based on its chemical properties. Benzophenone is polar molecule and, therefore, a polar solvent methanol was used as the diluent.

2.3. DSC

Differential scanning calorimeter (DSC) of Perkin Elmer/Pyris-1, USA, with a heating rate of 10°C/min and nitrogen flow of 5 mL/min was used for thermal analysis. The change in latent heat (ΔH) of control and treated ethanol was recorded from their respective DSC curves.

2.4. FT-IR

The FT-IR spectra were obtained from Shimadzu’s Fourier transform infrared spectrometer (Japan) in the frequency region of 400-4500 cm-1. FT-IR of control and treated samples of benzophenone was carried out to determine the effect of biofield energy treatment on molecular level like dipole moment, force constant, and bond strength in the compound. The samples were prepared by grinding benzophenone crystals with spectroscopic grade KBr into fine powder and then pressed into pellets.

2.5. UV-Vis Spectroscopy

UV spectra of control and treated samples of benzophenone were acquired from Shimadzu UV-2400 PC series spectrophotometer. Quartz cell with 1 cm and a slit width of 2.0 nm were used for analysis within the wavelength region of 200-400 nm.

3. Results and Discussion

3.1. GC-MS Analysis

The GC-MS spectra of control, and treated samples of benzophenone are presented in Figure 2. Mass spectra showed the PM peak at m/z = 182 in control and all treated benzophenone samples (T1, T2, and T3) with different intensities. However, the base peak was found at m/z = 105 in control, T1 and T3 samples. The intensity ratio of (PM+1)/PM and (PM+2)/PM are presented in Table 1 and percent change in isotopic abundance ratio was calculated and shown in Figure 3. Four major peaks at m/z= 182, 105, 77, and 51 were observed in both control and treated samples of benzophenone due to the following ions respectively: C13H10O+, C7H5O+, C6H5+, and C4H3 + ions. Peaks at m/z=105, 77, and 51 were observed due to the fragmentation of benzophenone to benzaldehyde, phenyl and buten-3-yne ions. All peaks were same for both control and treated samples and well matched with reported literature [14].

Table 1. GC-MS isotopic abundance analysis result of benzophenone.

The isotopic abundance ratio of (PM+1)/PM of benzophenone sample was slightly increased in T1 (5.79%) and T3 (4.47%) and decreased significantly in T2 (-44.87%) after biofield energy treatment. However, the isotope abundance ratio of (PM+2)/PM was increased significantly up to 22.64% in T3 (T1=20.84%, T2= 6.4 %,). The decreased isotopic abundance ratio of (PM+1)/PM in treated benzophenone may decrease μ (effective mass) and binding energy in this molecule with lighter isotopes, where the increased isotope abundance ratio of (PM+2)/PM in treated benzophenone may increase μ (effective mass) and binding energy of C-O bond. This may alter the property of the chemical bond and eventually property of the molecule. The transformation may be happened in the nuclear level due to the biofield treatment. It is expected that some of 16O may be interconverted to 18O atoms inside the molecule. Bond strength also plays an important role in kinetic effects due to the greater strength of the isotopic bonds such as 2H-12C bond relative to a 1H-12C bond [15].

3.2. HPLC Analysis

HPLC chromatogram of control and treated benzophenone is shown in Figure 4. The compounds have been separated into two peaks in both control and treated samples. The retention time (TR) of control benzophenone sample showed at 3.02 min with 89.1% relative intensity and another small peak at 2.6 min of 9.3% intensity, however after biofield treatment, this highly intense peak was shifted to 3.90 min with 97.6% intensity and the small peak at 3.03 min with 1.5% intensity. This increased TR may be attributed to the decreased polarity of benzophenone after biofield energy treatment. Further, the decreased polarity after biofield treatment may be due to change in planarity of the two benzene ring that resulted into higher TR [2, 16, 17].

3.3. DSC Analysis

DSC was used for thermal analysis of control and treated benzophenone samples. The change in heat (ΔH) of control and treated samples is presented in Table 2. It showed one strong endothermic transition at 208.01°C, however the endothermic transition was observed at 192.55°C after biofield energy treatment. The heat absorbed (ΔH) was increased from 65.33 J/g (control) to 505.76 J/g in treated benzophenone sample. The increase in ΔH in the treated sample was significantly increased by 674.16% as compared to the control. The increase in ΔH after biofield treatment could be due to alteration of intermolecular interaction (van der Waals interactions) in benzophenone crystal that might increase the thermal stability of the treated samples [16].

3.4. FT-IR Spectroscopic Analysis

The FT-IR spectrum of control and biofield energy treated benzophenone is showed in Figure 5. The vibrational peak at 3056 cm-1 was assigned to aromatic C-H stretching of the phenyl ring. The vibrational peak at 1654 cm-1 in control sample was assigned to C=O stretching vibration, that was shifted by 6 cm-1 to 1648 cm-1 after biofield energy treatment. This result was well supported by isotopic abundance ratio calculated from GC-MS. Due to the increased isotopic abundance ratio of 18O/16O in treated benzophenone, the effective mass (µ) increased and finally wavenumber decreased. The C-H in-plane bending vibrations were observed at ~1178 cm-1 and 1161 cm-1 in control and 1176 cm-1 and 1151 cm-1 in treated sample. The peaks observed between 1594 cm-1, and 1576 cm-1 in control and treated samples have been assigned to C-C stretching vibrations in aromatic ring. The FT-IR results after biofield treatment as compared to the control, have shown little changes in structural properties of the molecule except the C=O stretching frequencies, which lead to the changes in planarity and polarity of benzophenone crystal.

3.5. UV-Vis Spectroscopic Analysis

The UV spectra of control and treated samples of benzophenone are shown in Figure 6. The UV spectrum of control sample showed characteristic absorption peaks at λmax= 210 nm and 257 nm. However, the biofield treated sample showed characteristic absorption peaks at, 205 nm and 252 nm. Reported literature have suggested that the first strong band in the region of 240–300 nm corresponds to π-π* transitions and the weak n-π* band in the region of 320-370 nm [17]. In this UV-Vis spectra we have not observed any characteristics absorption peak in the region of 320-370 nm. This may be due to the weaker intensity of the n-π* band to observe in such a low concentration. The π-π* and n-π* bands show large and distinct shift with the polarity of the medium/solvent. Hence, it is hypothesized that biofield treatment might induced nonpolarity to the system that makes shift of the absorption positions. The π-π* band suffers a blue shift of around 5 nm which is indicative of the fact that there may be decreases in polarity of the molecule [17]. This observation is also supported by the higher TR of the treated sample in HPLC chromatogram.

4. Conclusions

Benzophenone was studied to see the effect of biofield treatment and compared for their isotope abundance ratio with the control one. GC-MS data showed that the isotopic abundance ratio of (PM+1)/PM was decreased to 44.87% and (PM+2)/PM was increased from 6.4% to 22.64% in treated sample as compared to the control. Biofield may also alter the planarity of the molecule which eventually alter the polarity and showed higher retention time (TR) in HPLC chromatogram. As a result a hypsochromic shift was observed in characteristic absorption position in UV-Vis spectra. Higher isotopic ratio (PM+2)/PM may be the reason for higher energy change in DSC study as compared to the untreated samples. It is assumed that biofield energy treatment may enhance the number of heavier 18O isotope in treated benzophenone that might be shifted the C=O stretching frequency towards lower energy region by increasing effective mass (µ). Thereby, the stability might increase in the organic small molecules of industrial importance by means of increasing effective mass (µ), which ultimately affect the shelf-life and efficacy of the final product.
