| 摘 要： | 采用点电荷模型,以平均共价因子N作为拟合参量和用Bkq作为晶场参量,运用完全对角化方法对Co(OH):晶体在90K时的吸收光谱进行了理论计算,并首次对其光谱进行了识别.同时讨论了温度对能级和配体键长的影响,从而认识到能级随温度的升高而按一定比例下降的变化关系.

| Abstract: | Adopting the model of point charge, in which covalent factor N regarded as modified parameters and Bkq regarded as crystal field parameter, the absorption spectra of Co(OH)2 single crystals have been recalculated and assigned at 90K by using the complete diagonal method. At the same time, the affection of temperature for the bond lengths and energy levels have been discussed. The proportion relations of the energy levels dropping with the temperature rising has been found. |
