Femtosecond Dynamics Of Diiodomethane Photodissociation in Solution

We present here ow new experimental and theoretical results concerning the low frequency boats in several polymnethtne dyes. Our studies show that the iduence of the solvation dynamica on the beat behavior is not reduced only to the time evolution of the chromophore spectra (the increare in beem contrast due to the haleburning eZZ is available.
