The Ultraviolet Flash Photolysis of Ozone and the Reaction of O(1D) with H2O

Abstract

The decomposition of gas mixtures containing ozone has been studied following a short duration u.v. light pulse. From an analysis of the O3 decomposition curves for O3:N2 and O3:H2O mixtures, it is shown that the relative rate of O(1D) reaction with H2O and N2 is [Formula: see text] It is also shown that less than6% of the O2, formed directly by photolysis, is in the [Formula: see text] state. The water catalyzed decomposition of ozone is also discussed.
