Crystal field and angular overlap treatment of the p2 configuration in low-symmetry ligand fields

Abstract

The p² configuration is treated by the crystal field and angular overlap methods in ligand fields of C_2v symmetry. The results are used in the discussion of the low-intensity bands in the visible and near-u.v. spectra of some Se^II and Te^II compounds. The spectra can be fitted to two parameters, a ligand-field splitting parameter and the bond angle ω. Calculated values of these parameters are discussed in relation to the structures and magnetic properties of the compounds in solution.
