✦ Synopsis

The reaction between BrO and HOs radicals: BrO + HO2 +HOBr + O2 ( 1 a) + HBr t 0s ( 1 b) was investigated using flash photolysis with UV absorption detection of the radicals, at 298 K and 760 Torr total pressure. BrO and HO1 radicals were formed in the flash photolysis of Br~/O,/Cl,/CH,OH/O,/He mixtures. The self-reaction of BrC radicals was also studied: BrOtBrO+2BrtOs

(Za)-rBrstOs (Zb). Kinetic simulations of decays of BrO radicals yielded k,= (3.4f 1.0)X lo-" cm3 molecule-' s-' and k2= (3.110.4)x lo-t2 cm3 molecule-' s-r.
