Abstract

Proceeding form the assumption that optical dd-transitions in high-T c superconducting compounds corresponds to Frenkel type excitations (or small radius excitons) their relaxation on free carriers is considered. It is shown that rather sharp changing of the elementary excitation spectrum at the superconducting transition temperature finds its reflection in the intensity of absorption with d-exciton creation (3d 9 → 3d 9 transitions in Cu2+ ions).
