Abstract
One of the basic assumptions we have used in deriving the equations for the density matrix of dynamic subsystem was assumption (3.96). The meaning of this assumption is that relaxation processes in the dissipative system are going on much faster than those of the dynamic subsystem. In particular, it may mean that electronic relaxation is going on much more slowly than that of vibrational modes of dissipative system. It refers, e.g. to electron transfer processes in condensed media. However, slow vibrational relaxation has been recently reported [51] in the experiments connected with electronic excitation processes. Theory of coupled electronic-vibrational relaxation was developed by Jortner [52] and applied for the analysis of the luminescence of electronically excited centres in condensed phases. Kenkre [53] has analyzed the situations of slow vibrational relaxation using the master equation approach.
