摘　　要：采用点电荷模型,以平均共价因子N作为拟和参量,考虑自旋-轨道相互作用,同时以Bkq作为晶场参量,运用配位场理论和完全对角化方法,对Cr3+:(NH4)2·C2O4.H2O晶体的吸收光谱进行了理论分析和识别,从理论上解释了Cr3+:(NH4)2·C2O4.H2O晶体的吸收光谱.By adoption of the point charge model, and the use of the average covalent factor N as the fitting parameter and taking into account the spin-orbit interaction, at the same time using Bkq as the crystal field parameter, the absorption spec tra of C r3＋ ： （ NH4 ）2 ·C204 · H20 single crystals were subjected to theoretical analysis and recognition by applying the ligand field theory complete diagonalization method and the absorption spectra of C r3＋ ： （ NH4 ）2 ·C204 · H20 single crystals were also interpreted in theory.
