The high order perturbation formulas of EPR parameters for d8 configuration in trigonal crystal field are derived.In our formulas, the contributions due to all excited states including singlets are considered. g⊥>g|| or g⊥ 0 or D< 0 are explained as due to the expanding or contracting of ligands along C3-axis. The formula obtained is applied to deal with EPR parameters of NiCl2 and NiSiF6· 6 H20 crystals.The agreement of theoretical calculation with experiment shows that the...

本文考虑到d~8电子组态中所有自旋三重态和自旋单态对基态的影响,用高阶微扰法导出了d~8电子组态在三角对称晶场下光谱和基态EPR普遍公式。发现在三角对称晶场下,d~8电子组态离子的g_(⊥)>g_(‖)或g_(⊥)0或D<0是以立方对称晶场为界,晶体中顺磁离子的配体沿C_3轴伸长或压缩所致。利用所得公式计算了NiCl_2和NiSiF_6·6H_2O晶体的EPR参量,其结果与实验吻合较好。

A theoretical description is given for the exchange interaction between two Cu~(2+) ions each sited in C_(2v) symmetry surroundings in the Cu(detc)_2 crystal. The point diople model of the crystal field theory is used to investigate the single Cu~(2+) ions respectively, which is the basis of the further consideration of Cu~(2+)-Cu~(2+) pairs exchange interaction, (?).

A theoretical description is given for the exchange interaction between two Cu~(2+) ions each sited in C_(2v) symmetry surroundings in the Cu(detc)_2 crystal. The point diople model of the crystal field theory is used to investigate the single Cu~(2+) ions respectively, which is the basis of the further consideration of Cu~(2+)-Cu~(2+) pairs exchange interaction, (?). The theoretical expressions of the transition energy levels, g-factors and zero-field splitting have been obtained using self-consistent-field (SCF) d-orbital theory, which gives the relation between EPR parameters and crystal structure with the Cu~(2+)-Cu~(2+)pairs consideration. The optical absorption spectra and EPR data, g-factor and zero-field splitting have been explained by the unified interpretation using only two parameters. The results of which are discussed.

本文利用晶场理论中的点电荷-电偶极模型,从“孤立络离子”近似下Cu~(2+)的光学性质和磁学性质的研究出发,探讨了晶体中Cu~(2+)-Cu~(2+)离子间相互作用对电子顺磁共振谱(EPR)的影响。以Cu(detc)_2晶体为例,首次用SCF-d轨道理论,解释了前人没法定量解释的零场分裂现象,建立了考虑Cu~(2+)-Cu~(2+)间相互作用后自旋哈密顿参量和晶格参数间的关系,从而首次从理论上给出了从孤立络离子近似到存在离子间相互作用时晶体的EPR谱的统一解释。计算结果表明:对于Cu(detc)_2,考虑Cu~(2+)-Cu~(2+)对的影响后,g-因子不变(这与实验结果符合),而零场分裂主要是旋轨耦合、晶场对称性以及Cu~(2+)-Cu~(2+)对间交换作用联合作用的结果。并对所得结果进行了讨论。
