Abstract

In the present paper we report on an analysis of the fine structure of the first excited quartet ⁴T2g of Mn⁴⁺ions which occupy the octahedral site in the Cs2GeF6 host crystal. The dynamic ⁴T2g ⊗ (eg + t2g) Jahn-Teller effect is considered in details, including the Ham effect of the reduction of the spin-orbit splitting and displacements of the ligands due to the combined effect of the aig and eg normal modes of the [MnF6]²~ octahedral complex. The electron-phonon coupling constants are evaluated using the experimental spectroscopic data. The value of the Jahn-Teller stabilization energy ^ejt = 438 cm ¹for the considered complex is estimated from both the Ham effect and the potential energy surface of the ⁴T2g excited state.
