中文摘要：

基于配位场理论,建立d3组态离子在三角晶场中的完全能量矩阵,采用完全能量矩阵的对角化计算方法,研究了绿宝石晶体Cr^3＋：Be3Al2（SiO3）6的光谱和EPR谱,理论值与实验值符合得很好.通过分析绿宝石晶体中（CrO6）^9-团簇的光谱和EPR谱,研究了配体在络合物中的极化现象.结果表明由于周围配位环境的影响,绿宝石晶体中（CrO6）^9-团簇内的O2^-离子存在较强的局域极化效应.

英文摘要：

By diagonalizing the complete energy matrix for d3 configuration ion in a trigonal ligand-field based on ligand-field theory,optical and EPR spectra of Cr^3 ＋ ：Be3Al2（SiO3）6 system are studied,the results of which are in good agreement with experimental facts. By analyzing optical and EPR spectra of （CrO6）9-cluster,the local polarization of oxygen ligands in （CrO6）^9-cluster are studied. Results show that oxygen ligands in （CrO6）^9-cluster exhibit remarkable polarization effect due to the effect of surrounding environment.
