摘要：

The temperature dependence of the rate coefficient for the atmospherically important radical-molecule reaction OH + HBr has been investigated between 76 and 242 K using a pulsed uniform supersonic flow reactor. The current work indicates that the rate coefficient shows significant inverse temperature dependence only below 150 K. These results verify that within the terrestrial atmosphere, the OH + HBr reaction manifests a temperature-independent bimolecular rate coefficient k = (1.2 +/- 0.2) x 10(-11) cm(3) s(-1).
