Abstract
An extension of femtochemistry to the gas-liquid transition region is reported for an elementary reaction, the dissociation and recombinatio n of iodine in supercritical argon reaching a density of 30.5 mol l-1. Three phenomena are systematically studied in the range 0 to 2000 bar of argon: the change of the coherent nuclear motion with solvent dens ity, the rate of predissociation, and the caging by the solvent. The a pproach offers a unique way for examining the dynamics in real time fr om the gas to the liquid density limit.
