摘　　要：本文考虑了ｄ８电子组态中所有自旋三重态和自族单重态项，并计及自旋－轨道耦合项Ｈｓｏ的影响，用不可约张量法导出了ｄ８电子组态在三角对称晶场下包括３Ｆ、３Ｐ、１Ｇ、１Ｄ、１Ｓ的哈密顿矩阵。从理论上研究了低温下Ｎｉ２ＣｄＣｌ６·１２Ｈ２Ｏ中Ｎｉ２＋离子的偏振吸收谱和精细分裂谱，理论结果与实验相符合。In this paper,considering the contribution of spin-triplet, spin--singlet(3d8ion) and spin--orbit coupling,we derive the Hamiltonian matrix of 3F, 3P, 1S, 1D, 1G, ion in D3d symmetry. Based on this matrix,the absorption spectra and the fine structure of Ni2+ in Ni2CdCl6.12H2O are studied. The restults agree well with the experimental data.
