A new computational method to account for the effect of anharmonicities on non-radhtive decay ratesofkge molecules in the statisti~l limit is given by using expansions of the generating functions which have been used successfully 'ffl multiphor;on processes.

We investigate the condltlons under which multilevel systems such as moIecules wiuch may undergo mtramolecular radiationless transitions could gwe rise to optlcal echoes when subJected to two successlve pulses.
An explanation is ghlen for the experimentally observed red-shift of the absorption band of molecules, in a moIecuIar beam, that have undergone radiationless transitions. A theoretical analysis shows that the effect originates from a decrease of the frequencies of the vibrational modes under the ele
