摘要: 本文提出一套在态叠加微扰理论基础上的INDO近似计算方法,把化学位移的计算推广到包含d和f轨道的一般情况。NMR化学位移计算方法应用量子力学态叠加微扰理论[1],可将分子中原子N的磁共振参数σN分成反磁贡献σNd,顺磁贡献σNp,原子M对N产生的贡献σNNM以及环流效应σNring.

Abstract: Bused on the Sum-Over-States Pertubation theory,we extencd the INDOmethod to make it useful for the calculation of the NMRchemical shift for the compounds including s,p,d and ? orbitals.All the formulae and results for the matrix elements (operators O=1/r,L,or L/r) neglecting the differential overlap are reported.
