The reaction of ClO with BrO has been investigated by two independent techniques, discharge flow-mass spectrometry and flash photolysis-UV spectrometry, over the temperature range 220--400 K and the pressure range 1--760 torr. Rate constants have been determined for three product channels; a) Br+ClOO, b) Br+OClO, and c) BrCl+O2. The rate constants for the overall reaction and each reaction branch were found to be inversely dependent on temperature and independent of pressure. The results for the temperature dependence of the overall rate constant from the discharge flow and flash photolysis studies are in excellent agreement and collectively disagree substantially with the only previous temperature dependence study. Also, in constrast to previous studies, the channel forming BrCl is found to be significant(≂8%). These kinetic measurements have an important impact on the modeling of Antarctic chemistry; for temperatures found in the Antarctic stratosphere the rate coefficients for the channels yielding ClOO and OClO are a factor of 2--3 larger than previously estimated. In addition, the BrCl channel, which has an impact on the nighttime partitioning of BrOx and the diurnal variability of OClO, has been omitted from previous atmospheric models. ¿ American Geophysical Union 1988
