Abstract

A theory of electronic transitions from a non-degenerated to a two-fold degenerated or quasi-degenerated electronic state in an impurity centre of a crystal is proposed. The coupling of optical electron(s) with non-totally symmetrical vibration(s) and with phonons are taken into account. The latter interaction results in the replacement of vibronic lines by phonon-assisted bands. The widths of bands, the rates of the energy relaxation of vibronic states and the shapes of optical spectra are calculated for some values of parameters.
