摘要: 本文提出了Z算符与角动量积算符相结合的广义积算符,用于描述高自旋弱耦合系统NMR实验谱。给出了高自旋系统在自旋耦合作用下的演变公式,Z算符在脉冲作用下的变化公式。以氘(D)为例,计算了重聚INEPT,DEPT和同核COSY实验谱,并对计算方法作了讨论。

Abstract: A New density operator formalism for describing high-spin nuclei systems-angular momentum product operator and Z operator was proposed. The product operator and {Z} operator evolution formulae were derived under the effect of spin-spin couplings and radio frequency pulses. The theory dercription can be used to analyse NMR multi-pulse experiments for high-spin nuclei systems. Re-focused INEPT, DEPT and Homonuclear Cosy for high-spin nuclei systems were calculated by using the new density operator. The Caculation method is discussed.
