Abstract : The decomposition of ozone has been studied following a short duration u.v. light pulse. From an analysis of the O3 decomposition curves for O3:N2, O3:N2:O2 and O3:O2 mixtures the relative rate constant for O(singlet D) deactivation by N2 and O2 is given. It is also shown that O2(singlet Sigma(sub g)(+)) is formed in at least 75% of the collisions in which O(singlet D) is deactivated by O2. The rate constants of the reactions O2(singlet Sigma(sub g)(+)) + O3 to 2O2 + O and O + O2 + O2 to O3 + O2 are found. (Modified author abstract)
