Coordination field analysis of rare earth complexes with triangular symmetry

The calculation of the complex matrixes in odd triangular symmetry was accomplished. The configurations of the coordination unit with various triangular symmetries and different ligand numbers were discussed. On the basis of the double-sphere coordination point-charge (DSCPCF) model, the detailed forms of the DSCPCF parameters Bk null null null null null null null null null null null null null null null m and the expressions of the perturbation...
