摘要:

采用赵敏光提出的双zeta d-轨道模型,通过拟合平均共价性因子N和电偶极矩μ,统一地解释了ZnS:Co2+的d-d跃迁谱和顺磁g因子,g因子的计算结果分别为2.2482(微扰法)和2.235(完全对角化方法),与实验值2.248符合得很好.文章对计算中遇到的轨道模型、微扰方法、参量拟合、双旋轨耦合及Jahn-Teller效应等有争议的问题作了阐释.

Abstract:

In this work, d-d transition spectra and paramagnetic g factor of ZnS:Co2+ are uniformly explained by fitting average covalent reduction factor N and the electric dipole moment of the ligand μ on the basis of Zhao's double zeta-d wave function. The calculated values of g factor 2.248 (perturbation) and 2.235 (CDP) agree well with experiment datum 2.248. Some controversial issues, such as orbital model, perturbation method, parameter fitting, double spin-obit coupling and Jahn-Teller effect, are well explained.
