摘要
本文利用 D_h 点群表象,建立了 d^8-C_(30) ~*的强场矩阵,进而从理论上计算出 CsMgCl_3:Ni^(2+)的吸收谱,零场分裂参量 D,g 因子,Zeeman 能量修正及顺磁共振条件等.计算结果和观测结果一致,从而解释了吸收谱及顺磁性质的起源.并讨论了激发态对基态的影响.
The complete strong-field matrices have been established for d^8 ions in C_3(?)* symmetry,onsidering the spin-orbit
interaction,within the O(?) point group representatives.Consequently,the optical absorption spectrum,the zero-field split-
ting parameter D,the paramagnetic g-factors and the Zeeman energy of the CsMgCl_3:Ni^(2+)crystals have been calculated
theoretically.The results are consistent with the experimental values.Thus the physics of the optical and the paramagnetic
properties are well understood.Also,the effect of the excited states on the ground-state properties has been discussed.
