Photolysis of Ozone at Low Pressures

Abstract

AbstractA technique has been developed for the determination of the quantum yield of ozone photolysis at low pressures. A continuous flow system was used, and the rate of ozone decomposition was calculated from changes in intensity of the chemiluminescent reaction between ozone and nitric oxide. Some preliminary determinations of relative quantum yields are presented, which appear to indicate that chain propagation processes are unimportant at pressures below about 0.5 Torr.
