摘要: 本文介绍在FX系列NMR谱仪上完成一维异核化学位移相关实验的方法。使用本文提出的"零强度法",即使在低磁场谱仪上,也能够通过测量几个13C谱以较高的精度确定出某些CH2基团两质子的化学位移之差。

Abstract: A method for one-dimensional heteronuclear chemical-shift correlation experiments on a FX-series NMR spectrometer is introduced.With the zero-intensity method proposed here,the chemical-shift difference of two protone for some CH2 groups can be accurately determined by measuring several 13C-spectra, even on a spectrometer with low magnetic field.

Key words: chemical-shift correlation experiment, zero-intensity method, NMR
