Quantum Yields for the Photodissociation of Iodine in Compressed Liquids and Supercritical Fluids

Quantum yields of photodissociation were determined for iodine in compressed liquid n-alkanes and supercritical CO₂ and xenon after laser excitation at 532 nm. The quantum yield decreases nearly linearly with increasing density. No cluster effects at low density were observed at this excitation energy. Our results are compared with molecular dynamics simulations and point at the importance of kinematic processes involved in the recombination dynamics of iodine.
