Abstract

In this contribution we analyze the electron-lattice coupling in a case of localized orbital triplet states using the emission, absorption and the excited state absorption (ESA) spectra of the d degree(s) complexes in CaWO₄ and CaMoO₄ crystals. We consider coupling to a fully symmetrical one-dimensional mode as well as to (epsilon) and (tau) ₂ Jahn-Teller (J-T) modes. Our method allows us to estimate the contribution of the J-T effect and coupling to the full symmetry breathing mode to the overall electron-lattice coupling energy. We also estimate anharmonicity of the lattice vibrations related to the spin-orbit coupling between the components of the luminescing triplet.
