✦ Synopsis

An extension of femtochemistry to the gas-liquid transition region is reported for an elementary reaction, the dissociation and recombination of iodine in supercritical argon reaching a density of 30.5 mol P-'. Three phenomena are systematically studied in the range 0 to 2000 bar of argon: the change of the coherent nuclear motion with solvent density, the rate of predissociation, and the caging by the solvent. The approach offers a unique way for examining the dynamics in real time from the gas to the liquid density limit.

We report new studies on the effect of solvent on the femtosecond dynamics of the dissociation and recombination of iodine in the gas-to-liquid transition region. The pressure of the solvent (helium, neon, argon and krypton) spans the range from 0 to 2500 bar, corresponding to solvent densities from
