摘要: 本文介绍一种产生不连质子的13C核NMR谱的脉冲序列,并对该序列提出了改进意见。在FX-90Q型NMR谱仪上证实了这种改进对提高累加效率和减小谱线的强度失真具有明显效果。

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.
