摘要： 合成Sm(TTA)_4·HP和Dy(TTA)_4·HP配合物, 测定了其紫外-可见-近红外溶液吸收光谱。应用DSCPCF模型在D~*_4场中推导了J值从1/2到15/2的矩阵元表达式, 并在分析R_EO_8配合单元对称性变化对f能级影响的基础上归属了光谱吸收峰。

Abstract: The complexes, Sm(TTA)_4·HP and Dy(TTA)_4·HP, have been prepared, and their UV-VIS-NIR absorption spectra measured. The matrix element expressions with I=1/2 to 15/2 of the configurations f~5 and f~9 in a D_4~* symmetry field were derived with Double Sphere Coordination Point Charge Field Model. And the influence of change in symmetry of complex unit R_EO_8 on the DSCPCF splitting of their levels was discussed. Based on theoretical ealcalation, the intra-f transition peaks in the absorption bands were assigned.
