摘要 采用半自洽场自由Ni2+的d轨道波函数和点电荷-偶极子模型,建立局部结构、光谱与电子顺磁共振(EPR)谱(零场分裂D和顺磁g因子)之间的定量关系.利用完全对角化方法(CDP)和高阶微扰方法,统一解释CdCl2∶Ni2+晶体的局部结构、光谱和电子顺磁共振谱(EPR),并比较两种计算方法得到的结果. Local structure, optical absorption spectra and electron paramagnetic resonance(EPR) spectra of CdCl2:Ni^2+ crystal are calculated in a semi-SCF d-orbit wave functions model for free Ni2. ions and a point-charge-dipole model. A complete diagonalization procedure(CDP) and high-order perturbation formulas are used. Results of two methods are compared.
