摘要: Biphenyl is used as an intermediate for synthesis of various pharmaceutical compounds. The objective present research was to investigate the influence biofield treatment on physical, spectroscopic and thermal properties biphenyl. study performed in two groups (control treated). control group remained untreated, given treated group. biphenyl were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, Ultraviolet-visible (UV-Vis) spectroscopy surface area analysis. showed decrease intensity XRD peaks compared control. Additionally, crystallite size decreased 16.82% with respect (72.66oC) increase melting temperature (70.52oC). However, latent heat fusion (∆H) substantially changed 18.75% (155.14oC) alteration maximum decomposition (Tmax) sample (160.97oC). This stability Spectroscopic (FT-IR UV-visible) no chemical nature Surface through Brunauer-Emmett-Teller (BET) analyzer significant Overall, result demonstrated that has affected physical
