✦ Synopsis

The photodissociation of iodine has been studied in the@ phase by Iaser fIash photoiysis. The decrease of the quantum yield with increasing ethane and propane pressure has been intirpreted in terms of the cage effect. As the tempemture is increased a less pronounced czge effect is observed_ The trends in the measured quantum yields with chaag& temperature and pressure agree with model cakulations for dissociation in a viscous contimmm. However the simple model applied is not useN for quantitative predictions A smzll decrease of the second order rate constant for iodine atom recombiition Ius been observed with increasing temperature.
