摘要：

The dynamics of I2 dissociation and recombination (caging) in a macrocluster are reported, covering the femtosecond to picosecond time domain. Both the exit-channel and recombination dynamics are observed and related to solute-solvent interactions. The dissociation involves bond breakage on bound/repulsive potentials with concomitant evaporation of the solvent shell. The caging is accompanied by relaxation of the system and/or diffusion of the free iodine atoms prior to reforming the I2 bond. Molecular dynamics are used to compare with experiments.
