| 摘 要： | 可用于多脉冲作用下 AX 弱耦合自旋系统的相干图描述方法,其主要优点是简便明瞭,便于计算机程序编排模拟,而且相干图方法突出了单个脉冲或脉冲序列段的作用,这对于新的脉冲序列的设计具有启发作用。本文将此方法推广至 AMX、AX_2和 AX_3等典型多自旋弱耦合系统,并以 DEPT 实验及同核和异核 Relay 相干实验为例作了说明。

| Abstract: | The main advantoges Coherence chart method which can be used for describing AX weakly coupling spin system applied by multipulse sequence are simple and (?)asy to be used for computer simulation.The role of single pulse or period of pulse sequence is stressed in the method so that it is very useful for the design of new pulse sequence and analysis of pulse sequence introduced before.In this paper coherence chart method is popularized to typical multispin weakly coupling systems such as AMX,AX_2 and AX_3.Applied examples for DEPT experiment,homon- uclear and hetronuclear relay coherence experiment are given. |
