✦ Synopsis

The photochemistry of aqueous solutrons of iodide and bromide is investigated in the presence of high concentrations (2 x 10m2 M < C c 1.2 M) of nitrous oxide. In the iodide system, the photo-oxidation yfeids depend markedly on [N20]. The effect is attributed to the scavenging of solvated electrons from a photachermcal cage. The role of geminate (cage) recombination in chloride and bromide solutions is discussed. The process does not occur in the case of Cf. In bromide solutions, the observed independency of the yields on [N20] does not provide a defmite answer as to the efficiency of the cage process.
