Abstract
The rate constants for the reactions of H+Br2 and D+Br2 were measured by employing a pulse radiolysis–resonance absorption technique. The rate constants could be expressed by the following Arrhenius equations between 214 and 295 K: k(H+Br2) =6.7×10−10 exp(−680/T), k(D+Br2)=6.0×10−10 exp(−720/T), in units of cm3 s−1. Sudden transition state theoretical calculations were performed on the basis of modified LEPS surfaces. The calculated results were compared with the experimental ones.Keywords
