WebFT-IR spectra of thiourea showed upstream shifting of NH2 stretching peak (3363→3387 cm-1) as compared to control, which may be due to decrease in N-H bond length. Also, the change in frequency of N-C-S bending peak (621→660 cm-1) was observed in treated thiourea that could be due to some changes in bond angle after biofield treatment. WebCopper complexes with 1,3-disubstituted thiourea derivatives, all containing 3-(trifluoromethyl)phenyl tail and 1-alkyl/halogen-phenyl substituent, were synthesized.
