✦ Synopsis

It is shown how a many-level radiationless model may be replaced by an effective one involving only the states of interest. When the coupling between the states of interest and the dissipative quasicontinuum is assumed to be not a constant one, the effective interaction can exhibit a non-markovian feature even in the statistical limit. Then, irradiation frehts the intensities of which are not negIigiiIe compared to the excited state Iinewidth, are shown to reduce the coupling betaeen the system of interest and its effective "thermal bath". The previsions of the theory are checked by comparison with results obtained dire&y from the diagonahzation of the Morokuma and Freed hamiltonian.
