Abstract

Time-resolved tunable diode laser spectroscopy has been used to measure the production of HCl in the reaction of OH and ClO radicals. The OH and CiO radicals were formed from the 308 nm laser photolysis of mixtures containing O₃, Cl₂, and H₂O. Computer simulations of the chemistry were used to derive a rate coefficient of (1.25 ± 0.45) × 10^-12 cm³ molecule^-1 S^-1 for the title reaction at 298 K. This reaction rate, which corresponds to a branching fraction of (6.5 ± 3.0)% relative to the currently recommended rate coefficient for the overall reaction, confirms that the reaction will have a substantial impact on the partitioning of chlorine compounds in the stratosphere.
