摘要
用同核化学位移相关谱和同核RELAY谱等二维NMR方法完全归属了复杂天然有机化合物人参皂甙Rb<sub>1</sub>的<sup>1</sup>H NMR谱线,并用积算符方法证实一级和二级RELAY实验中观察到的意外交叉峰是通过远程偶合传递的RELAY信号。
The 1H chemical shifts of ginsenoside-Rb1 were assigned completely by means of COSY and homonuclear RELAY spectroscopy. Some external cross peaks were observed in single and mutiple homonuclear RELAY spectra, the results of calculation of product operator indicated that these external cross peaks originated from the relayed coherence transfer of long range coupling interaction of protons.
