| Abstract: | The photolysis of iodine has been studied in the gas phase using laser flash photolysis at 6943 A. The dependence of the quantum yield on the pressure has been investigated in the range 0.1–1000 atm for several inert gases. For Kr, Xe, O2, CO2, CH4, C2H6 and C3H8 a decrease of the quantum yield with increasing pressure was obtained; for He, Ne, Ar and H2 no effect could be observed. These results may correspond to a photolycitc cage effect of iodine in the gas phase analogous to that known from the liquid phase. |
