Abstract

Detailed time-resolved photodissociation and caging dynamics are reported for an I₂(OCS)₁₁ model system. The observed product channel-dependent nuclear coherence in the dissociated chromophore reflects complex dynamics of the solvent cage. The evolving pump-probe product distribution offers the possibility of incoherent control of two-photon dissociation pathways by appropriately delaying the probe laser pulse. As an example of such control, I₂(OCS₂ is produced most effectively by a limited set of pump-probe excitations. We emphasize generality of these results that relate to caging dynamics in nay cluster ions.
