|Characterization of Physical, Thermal and Spectral Properties of Biofield Treated 2,6-Dichlorophenol|
2,6-Dichlorophenol (2,6-DCP) is a compound used for the synthesis of chemicals and pharmaceutical agents. The present work is intended to evaluate the impact of Mr. Trivedi’s biofield energy treatment on physical, thermal and spectral properties of the 2,6-DCP. The control and treated 2,6-DCP were characterized by various analytical techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, and ultra violet-visible spectroscopy (UV-vis) analysis. The XRD results showed the increase in crystallite size of treated sample by 28.94% as compared to the control sample. However, the intensity of the XRD peaks of treated 2,6-DCP were diminished as compared to the control sample. The DTA analysis showed a slight increase in melting temperature of the treated sample. Although, the latent heat of fusion of the treated 2,6-DCP was changed substantially by 28% with respect to the control sample. The maximum thermal decomposition temperature (Tmax) of the treated 2,6-DCP was decreased slightly in comparison with the control. The FT-IR analysis showed a shift in C=C stretching peak from 1464→1473 cm-1 in the treated sample as compared to the control sample. However, the UV-vis analysis showed no changes in absorption peaks of treated 2,6-DCP with respect to the control sample. Overall, the result showed a significant effect of biofield energy treatment on the physical, thermal and spectral properties of 2,6-DCP. It is assumed that increase in crystallite size and melting temperature of the biofield energy treated 2,6-DCP could alleviate its reaction rate that might be a good prospect for the synthesis of pharmaceutical compounds.

Hence, by capitalizing on the unique biofield energy treatment and pharmaceutical properties of 2,6-DCP, this research work was perused to investigate the impact of biofield energy treatment on the physical, thermal and spectral properties of this compound. The control and treated samples were analyzed using various analytical techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, and ultra violet-visible spectroscopy (UV-vis) analysis.
2. Materials and Methods
2,6-DCP was procured from S D Fine Chemicals Pvt. Limited, India. The sample was divided into two parts; one was kept as the control sample while the other was subjected to Mr. Trivedi’s unique biofield energy treatment and coded as treated sample. The treated sample was in sealed pack and handed over to Mr. Trivedi for biofield energy treatment under laboratory condition. Mr. Trivedi gave the energy treatment through his unique energy transmission process to the treated samples without touching it.
2.1. X-ray Diffraction (XRD) Study
XRD analysis of control and treated 2,6-DCP was evaluated using X-ray diffractometer system, Phillips, Holland PW 1710 which consist of a copper anode with nickel filter. XRD system had a radiation of wavelength 1.54056 Å. The average crystallite size (G) was computed using formula:
G = kλ/(bCosθ)
Here, λ is the wavelength of radiation used, b is full-width half-maximum (FWHM) of peaks and k is the equipment constant (=0.94). Percentage change in average crystallite size was calculated using following formula:
Percentage change in crystallite size = [(Gt-Gc)/Gc] ×100
Where, Gc and Gt are denoted as crystallite size of control and treated powder samples respectively.
2.2. Differential Scanning Calorimetry (DSC)
The control and treated 2,6-DCP samples were analyzed using Pyris-6 Perkin Elmer DSC at a heating rate of 10ºC/min and the air was purged at a flow rate of 5 mL/min. The predetermined amount of sample was kept in an aluminum pan and closed with a lid. A reference sample was prepared using a blank aluminum pan. The percentage change in latent heat of fusion was calculated using following equations:
Where, ΔHControl and ΔHTreated are the latent heat of fusion of control and treated samples, respectively.
2.3. Thermogravimetric Analysis-Differential Thermal Analysis (TGA-DTA)
A Mettler Toledo simultaneous TGA and differential thermal analyzer (DTA) was used to investigate the thermal stability of control and treated 2,6-DCP samples. The heating rate was 5ºC/min and the samples were heated in the range of room temperature to 400ºC under air atmosphere.
2.4. FT-IR Spectroscopy
The FT-IR spectra were recorded on Shimadzu’s Fourier transform infrared spectrometer (Japan) with the frequency range of 4000-500 cm-1. The treated sample was divided into two parts T1 and T2 for FT-IR analysis.
2.5. UV-Vis Spectroscopic Analysis
A Shimadzu UV-2400 PC series spectrophotometer with 1 cm quartz cell and a slit width of 2.0 nm was used to obtain the UV spectra of the control and treated 2,6-DCP samples. The spectroscopic analysis was carried out using wavelength in the range of 200-400 nm and methanol was used as a solvent. The biofield energy treated sample was divided in two parts T1 and T2 for the UV-Vis spectroscopic analysis.
3. Results and Discussions
3.1. XRD Study
XRD is a non-destructive technique that is used to evaluate the crystalline nature of the materials. The XRD diffractogram of control and treated 2,6-DCP are depicted in Figure 1. The XRD diffractogram of the control and treated 2,6-DCP samples exhibited intense peaks that indicated the crystalline nature of the samples. The XRD diffractogram of control 2,6-DCP showed well defined intense peaks at Braggs angle (2θ) equal to 15.69º, 17.37º, 22.17º and 27.97º. However, the treated 2,6-DCP compound showed the presence of intense XRD peak at 2θ equal to 15.48º. The comparative evaluation of the control and treated 2,6-DCP samples showed shifting and increase in the intensity from Braggs angle (2θ) equal to 15.69º→15.48º in the treated sample as compared to control sample. It was reported previously that if any crystallite in the sample are strained (compressed) by the same amount this may result in a shift in XRD diffraction peaks . Hence, it is assumed that biofield energy treatment might cause homogeneous strain that induced a shift in the XRD peak. Nevertheless, the other XRD peaks originally present at 17.37º, 22.17º and 27.97º in the control sample were disappeared or diminished in the treated sample. This may be correlated to decrease in crystallinity of the treated sample as compared to the control. Additionally, the change in crystal morphology on biofield treated sample might cause changes in the relative intensity of the XRD peaks with respect to control .
The crystallite size of control and treated 2,6-DCP were calculated using Scherrer formula and results are presented in Figure 2. The crystallite size of control 2,6-DCP was 80.35 nm and after biofield energy treatment it was increased up to 103.62 nm. The result suggested 28.94% increase in crystallite size of treated 2,6-DCP with respect to the control sample. It was reported that the structural defects such as interstitials, vacancies, dislocations, and layer faults cause inhomogeneous strain within the crystallite. Lalitha et al.  and El-kadry et al.  reported that a decrease in internal micro-strain in materials causes an increase in the crystallite size. Additionally, Chen et al. elaborated that decrease in micro-strain leads to a reduction in inter-planar spacing and this minimizes the stacking fault probability in the materials . Hence, it is assumed here that biofield energy treatment might cause a decrease in internal microstrain and this lead to a decrease in the inter-planar spacing and resultant increase in the crystallite size. It was reported previously that rate of a chemical reaction could be enhanced by elevation in crystallite size of the compounds . Since, 2,6-DCP is used as intermediate for the synthesis of compounds hence, increase in crystallite size might improve its reaction rate and reaction yield.
3.2. DSC Characterization
DSC is a thermal analysis technique used for the evaluation of melting temperature, glass transition and latent heat of fusion of the materials. DSC thermograms of the control and treated samples are presented in Figure 3. DSC thermogram of the control 2,6-DCP showed a sharp endothermic peak at 67.68ºC due to melting temperature of the sample. However, the treated 2,6-DCP sample showed no change in melting temperature (67.30ºC) as compared to the control.
The latent heat of fusion of control and treated 2,6-DCP were recorded from the DSC thermograms and data are depicted in Table 1. The latent heat of fusion of control 2,6- DCP was 136.84 J/g and after treatment it was decreased to 98.53 J/g. The result suggested that the latent heat of fusion of treated sample was decreased by 28% as compared to the control. The latent heat of fusion is the energy absorbed during phase change of material from solid to liquid. It is assumed that biofield treatment might alter the energy stored in the treated 2,6-DCP sample that lead to a reduction in the latent heat of fusion of the sample. Moreover, it is hypothesized that the treated sample might be present in the high-energy state that led to a reduction in latent heat of fusion. Recently, from our research group it was reported that biofield energy treatment effectively altered the latent heat of fusion of thymol and menthol .
3.3. TGA Analysis
TGA thermograms of control and treated 2,6-DCP are presented in Figure 4. The TGA thermogram of the control 2,6-DCP started to degrade thermally at 130ºC, and it terminated at 172ºC. The sample lost 48.42% weight during this process. However, the TGA thermogram of treated 2,6- DCP showed thermal degradation at 130ºC, and this step terminated at around 170ºC. During this process, the sample lost 51.52% of its initial weight.
The DTA thermogram of the control and treated 2,6-DCP are presented in Figure 4. The DTA thermogram of control 2,6-DCP showed two endothermic peaks at 68.22ºC and 156.24ºC. The former peak was mainly due to melting temperature of the compound. While the later peak was due to thermal decomposition of the compound chains. The treated 2,6-DCP also showed two endothermic peaks at 69.08ºC and 155.99ºC. The first endothermic peak was due to melting temperature and second was due to the thermal decomposition. This showed a slight increase in melting temperature of the treated sample as compared to the control. This was probably due to biofield energy treatment that might increase the intermolecular interaction in the treated sample and resultant increase in melting temperature. It was reported that chlorophenol derivatives can form strong hydrogen bond complexes with other molecules . Similarly, 2,6-DCP compound also have a stronger tendency to intermolecular hydrogen bond formation . Therefore, it is assumed that biofield energy might absorbed in the treated 2,6-DCP that leads to the formation of hydrogen bond which ultimately increases the melting temperature.
The Derivative thermogravimetry (DTG) thermogram of control and treated sample are shown in Figure 4. The DTG thermogram of the control sample showed maximum thermal decomposition temperature (Tmax) at 147.15ºC and it almost remained unchanged in the treated sample (146.41ºC). This suggested no significant change in Tmax of treated 2,6-DCP after the biofield treatment.

3.4. FT-IR Spectroscopy
The FT-IR spectra of control and treated 2,6-DCP are depicted in Figure 5. The FT-IR spectrum of the control sample showed a broad peak at 3448 cm-1 that was due to OH stretch of the phenol group. Whereas, in case of treated samples (T1 and T2), it appeared at 3446 and 3443 cm-1, respectively. The C=C stretching peak was observed in the region of 1448-1577 cm-1 in the control, treated samples (T1 and T2) samples. The characteristic C-Cl stretching vibration peak was appeared at 837 cm-1 in all the control and treated (T1 and T2) 2,6-DCP samples. The C-H out of plane bending peaks were observed in the region of 603-767 cm-1 in the control and T1 sample. However, the T2 sample showed in the region of 605-779 cm-1. The C-H in plane bending peaks were appeared at 1149 cm-1 in the control and treated samples (T1 and T2). The C-O stretch was appeared at 1066 cm-1 in all the control and treated 2,6-DCP samples. The FT-IR results were well supported by the literature . Overall, the result showed an upward shift in C=C stretching peak from 1464→1473 cm-1 in the treated sample as compared to the control. Therefore, it is presumed that biofield energy treatment might increase the dipole moment of C=C bond as compared to the control sample .
3.5. UV-visible Spectroscopy
The UV-visible spectroscopy was used to investigate the chemical changes in the 2,6-DCP after biofield treatment. The UV spectra of control and treated 2,6-DCP samples are shown in Figure 6. The UV spectrum of control sample showed an absorbance peaks at 285, 278 and 205 nm. Nevertheless, the treated sample showed no changes in absorption peaks which were evidenced at 285, 278 and 205 nm in the treated 2,6-DCP (T1 and T2) samples, respectively . Overall, the UV results showed no changes in absorption peaks in biofield energy treated samples as compared to the control. Hence, it is suggested that the biofield treatment did not disturb the energy gap between highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO)  in the treated samples, and it was found similar to the control sample.
Fig. 6. UV-vis spectra of control and treated 2,6-dichlorophenol (T1 and T2).
In summary, the XRD results revealed a decrease in intensity and increase in crystallite size of the treated 2,6- DCP as compared to the control sample. It is hypothesized that biofield treatment could have provided the energy that caused a reduction in dislocation density and increase in crystallite size. The DTA result showed a slight increase in melting temperature of the treated 2,6-DCP as compared to the control. However, TGA and DTG analysis showed no changes in onset temperature and Tmax of the treated sample. The FT-IR analysis showed alterations in wavenumber of C=C group stretching of the treated samples as compared to the control sample. It was presumed that it might be due to the increase in dipole moment of the C=C bond as compared to the control sample. Overall, the result showed the impact of biofield energy treatment on physical, thermal and spectral properties of 2,6-DCP. The increase in crystallite size and minimal increase in melting temperature of the biofield energy treated 2,6-DCP might improve its reaction rate thus, it could be utilized as intermediate for the synthesis of pharmaceutical compounds.
