摘要: 基于Xα-SW法数值波函数,从微扰理论出发,计算了过渡金属配合物中CO、CS、CN和C5H5配体中的13C核磁共振顺磁化学位移σp及反磁性化学位移σd贡献.结果能反映实验趋势,并从电子结构及成键角度进行了讨论.

Abstract: The results for the first overlaping sphere Xa-SWchemical shift calculation are shown to reproduce the trends in13C NMRexperiments for the CO, C9, CNand C5H5 ligands in transition metal complexes Ni(CO)4, Cr(CO)5CSand Fe(CBH5)(CO)2CN.The relationship between the chemical shifts with the electronic structure and bonding have been discussed.
