VIBRATIONAL RELAXATION IN THE EXCITED ELECTRONIC STATE AND THE DEPOLARIZATION OF EMISSION

The spectral and polarization characteristics of the resonance secondary emission, such as the first order Raman scattering and hot luminescence (multiphonon Raman tail), are examined for multimode systems with a broad absorption band (i.e. strong vibronic coupling) on the example of cubic impurity centers. The transform method is generalized for nontotally symmetric modes
