摘要/Abstract

摘要： 提出一种描述自旋为1/2的强偶AB自旋体系多脉冲NMR实验的密度算符演化的方法,推导了自旋算符的自由演化公式,具体描述了极化转移INEPT实验和二维DQ-INADEQUATE实验。该方法物理意义直观,计算量较小。

Abstract: A new formalism was proposed to describe the evolution of density operators in multi-pulse NMR experiments for the strongly coupled AB spin systems(I=1/2); The evolution formula of spin operators were derived.The polarization transform INEPT experiment and two-dimensional DQ-INADEQUATE experiment were deseribed. The formalism is distinct on physical meaning and requires less ealculation.

Key words: Strongly coupled AB systems, NMR experiments, Density operator foimalism
