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-(OCS)2 is produced most effectively by a limited set of pump-probe excitations. We emphasize generality of these results that relate to caging dynamics in any cluster ions.
