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~(13)C谱以较高的精度确定出某些CH_2基团两质子的化学位移之差。
This article describes the FX series of NMR spectrometer to complete the one-dimensional nuclear chemical shift correlation experiment method. Using the zero intensity method proposed in this paper, the difference in chemical shifts between two protons of some CH 2 groups can be determined with high accuracy by measuring several 13 C spectra even on low magnetic field spectrometers.
