Dynamic Jahn-Teller effect for V²+ in MgO single crystal.
In this paper we studied the dynamic Jahn-Teller effect in the excited state (4)T(2g) of the V(2+) ions doped in MgO crystal, in octahedral coordination. Calculation of the fine structure of the energy levels in the frame of crystal field theory, estimation of the vibronic coupling constants and the Jahn-Teller stabilization energy are presented. The dynamic Jahn-Teller effect in the lowest excited (4)T(2)(g) state of the V(2+) ions is considered using the Ham effect and analysis of the displacements of ligands, due to the combined effect of the a(1)(g) and e(g) normal modes of the obtained octahedral cluster.
