Ammonium acetate and ammonium chloride are the white crystalline solid inorganic compounds having wide application in synthesis and analytical chemistry. The aim of present study was to evaluate the impact of biofield treatment on spectral properties of inorganic salt like ammonium acetate and ammonium chloride. The study was performed in two groups of each compound i.e., control and treatment. Treatment groups were received Mr. Trivedi’s biofield treatment. Subsequently, control and treated groups were evaluated using Fourier Transform Infrared (FT-IR) and Ultraviolet-Visible (UV-Vis) spectroscopy. FT-IR spectrum of treated ammonium acetate showed the shifting in wavenumber of vibrational peaks with respect to control. Like, the N-H stretching was shifted from 3024-3586 cm-1 to 3033-3606 cm-1, C-H stretching from 2826-2893 cm-1 to 2817-2881 cm-1, C=O asymmetrical stretching from 1660-1702 cm-1 to 1680-1714 cm-1, N-H bending from 1533-1563 cm-1 to 1506-1556 cm-1 etc. Treated ammonium chloride showed the shifting in IR frequency of three distinct oscillation modes in NH4 ion i.e., at ν1, 3010 cm-1 to 3029 cm-1; ν2, 1724 cm-1 to 1741 cm-1; and ν3, 3156 cm-1 to 3124 cm-1. The N-Cl stretching was also shifted to downstream region i.e., from 710 cm-1 to 665 cm-1 in treated ammonium chloride. UV spectrum of treated ammonium acetate showed the absorbance maxima (λmax) at 258.0 nm that was shifted to 221.4 nm in treated sample. UV spectrum of control ammonium chloride exhibited two absorbance maxima (λmax) i.e., at 234.6 and 292.6 nm, which were shifted to 224.1 and 302.8 nm, respectively in treated sample. Overall, FT-IR and UV data of both compounds suggest an impact of biofield treatment on atomic level i.e., at force constant, bond strength, dipole moments and electron transition energy between two orbitals of treated compounds as compared to respective control.
