A rapid and highly selective method for the identification of 40 kinds of organophosphorus pesticides was developed using 31P Fourier Transform Nuclear Magnetic Resonance with the 1H complete decoupling method. Chemical shifts referenced by 85% H3PO4 were within -7 to 100 ppm, and there was no overlapping one among the organophosphorus pesticides tested. It is clear that the 31P chemical shift is sensitive to the changes of the molecular structure. This method has been also proved to have high capability in selecting 31P atom contained in the material which includes water and other impurities.
