摘　　要：应用三角晶场中d2 (d8)电子组态的包括静电相互作用和自旋 轨道耦合相互作用的强场能量矩阵 ,采用完全对角化方法 ,精确地计算了具有C3V 对称的Ni2 +:LiNbO3 的光学吸收谱和EPR谱。By applying the energy matrix elements, including Coulomb interaction and spin-orbit coupling, of the strong field coupling scheme for d(2) (d(8)) electron configuration in trigonal crystal field and adopting the method of complete diagonalization, we calculate the optical spectra and the EPR spectrum of Ni2+ : LiNbO3 with C-3V symmetry. The results agree well with the values measured experimentally.
