Abstract: Intensity modulated 31P NMR spectra were obtained by using the pulse sequence in a FT-80A spectrometer. Spin-echo techque for signal assignment could be applied to systems with direct couplings (31P-1H) and long-range couplings (31P-O-C-1H) fragments. Some applications to the dialkyldithiophosphoric acids, dialkyl phosphonates and other phosphorus containing compounds are discussed.
