【Abstract】 A pulse sequence for generating the 13C-NMR spectra of nonprotonated carbons is introduced. A suggestion for improving this sequence is offered. It has been shown on a FX-90Q NMR spectrometer that this improvement can obviously increase the accumulation efficiency and decrease the peak intensity distortion更多还原
