In this Communication we report our first study of real-time reaction dynamics in finite size clusters. The reaction is of the type AH + Sn, where the proton transfer (bimolecular) dynamics is examined as the acid AH is solvated with different number of molecules, n = 1,2,... etc. This is in continuation of out effort to study reaction dynamics in real-time , but now extending the scope of the previous collisionless (solvent free) condition to a range where condensed phase effects can play a role. Of particular interest to us is the condition at which solvation induces vibrational relaxation and modifies IVR. Real-time studies of reactions in clusters offer great opportunities for obtaining the rates directly  and for examining these solvation processes under controlled conditions in molecular beams. Such stepwise solvation by beam methods has been advanced for a variety of systems spanning small molecules , large molecules , hydrogen-bonded systems , and electrons .
