Abstract
An extension of femtochemistry to the gas—liquid transition region is reported for an elemantary reaction, the dissociation and recombination 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 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.
