【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.更多还原
