Kinetics of the BrO + ClO reaction and implications for stratospheric ozone

The first direct measurements of the rate constant and product distribution of the BrO + ClO reaction as a function of temperature is reported. It is shown that this reaction could account for a large fraction of the springtime ozone depletion over Antarctica and provide a source of chlorine dioxide...

Description
Summary:The first direct measurements of the rate constant and product distribution of the BrO + ClO reaction as a function of temperature is reported. It is shown that this reaction could account for a large fraction of the springtime ozone depletion over Antarctica and provide a source of chlorine dioxide of sufficient magnitude to explain the recent measurements of this species in the Antarctic atmosphere, provided that the stratosphere contains a sufficient quantity of bromine.
