Nitrophenols are the synthetic organic chemicals used for the preparation of synthetic intermediates, organophosphorus pesticides, and pharmaceuticals. The objective of the present study was to evaluate the effect of biofield energy treatment on the isotopic abundance ratios of PM+1/PM, and PM+2/PM in o- and m-nitrophenol using the gas chromatography-mass spectrometry. The o- and m-nitrophenol were divided into two parts - one part was control sample, and another part was considered as biofield energy treated sample, which received Mr. Trivedi's biofield energy treatment (The Trivedi Effect®). The biofield energy treated nitrophenols having analyzed at different time intervals were designated as T1, T2, T3, and T4. The GC-MS analysis of bot...
