摘要:

建议了一种采用考虑重叠修正项的多重散射Xα自洽场方法,结合不可约张量方法求解过渡金属配合物价电子体系多电子Schrodinger方程的方法,并将其应用到Cr3+配合物光谱的计算,其计算结果与实验结果的方均根偏差仅1.5kcm-1,同时分析了Xα方法中重叠修正项对配合物电子结构以及光谱计算结果的影响,以及选用的组态对计算结果的影响.

Abstract:

A new way is developed for calculating the d-d excited energies by resolving many-electron Schrodinger equation based on MS-Xα method with overlapping atomic sphere and irreducible tensor method. As its applications, the d-d excited energies of Cr3+ complexes are calculated, and the root-mean-square devitation between calculated and experimental results are about 1.5kcm-1. The influence of overlapping term in MSXα equation on the electronic structure and d-d excited spectra of Cr3+ complexes are discussed.
