Flash photolysis study of the recombination of chlorine atoms in the presence of various inert gases and NO

The recombination of chlorine atoms has been investigated by flash photolysis in the inert gases He, Ne, Ar, N₂, CO₂, CF₄, SiF₄, SF₆, and C₂F₆. The pressure dependence of the reaction has been measured between 0.5 and about 100 atm for He, N₂, and CO₂. Experiments on the NO-catalyzed recombination of chlorine in the presence of He (0.5–100 atm) permitted a determination of the falloff curve of the reaction Cl+NO(+He)→ClNO(+He).
