摘要

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.

Abstract: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 spectra of Cr3+:(NH4)2?C2O4?H2O single crystals were subjected to theoretical analysis and recognition by applying the ligand field theory complete diagonalization method and the absorption spectra of Cr3+:(NH4)2?C2O4?H2O single crystals were also interpreted in theory.
