Abstract
The temperature dependence of the rate coefficient for the atmospheric ally important radical-molecule reaction OH + HBr has been investigate d between 76 and 242 K using a pulsed uniform supersonic flow reactor. The current work indicates that the rate coefficient shows significan t inverse temperature dependence only below 150 K. These results verif y that within the terrestrial atmosphere, the OH + HBr reaction manife sts a temperature-independent bimolecular rate coefficient k = (1.2 +/ - 0.2) x 10(-11) cm(3) s(-1).
