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.
