EPR determination of absolute rate constants for the reactions of h and oh radicals with hydrogen bromide

Quantum dynamics study of H + DBr and D + HBr reaction

“…In order to further verify the accuracy of the PESs by Han et al, we provide the calculated rate constants for the H + HBr abstraction reaction in Fig. 6, along with experimental measurements [4][5][6][7][8][9] and theoretical results [14] of Xie et al It is shown that the slope of our rate constants agrees with the theoretical result of Xie et al very well, with the present theoretical result slightly larger than the calculated results of Xie. We speculate that the neglect of the Coriolis coupling may mainly account for the difference between present and Xie's result.…”

“…Interest in the reactivity of H + HBr reaction dates back 30 years. The reaction rates for the H + HBr abstraction reaction have been measured by several different groups [4][5][6][7][8][9].…”

Reactions of OH radicals with inorganic compounds in the gas phase

“…The recommended values from the two evaluations [5,6] (Table XVI) differ because different determinations were taken into account in each case. The higher value, (6.64-0.6) x 1012, has been obtained in most recent determinations [231,233,234]. The reason for the discrepancy is not clear although it has been attributed [234] to incorrect determination of HBr concentration due perhaps to losses of HBr by absorption on the vessel walls.…”

A consensus view of the temperature dependence of the gas phase reaction: OH + HBr → H2O + Br

“…In some cases the purely statistical errors are shown to underrepresent the true errors and in these cases we report error bars which encompass the observed spread in experimental measurements of rate coefficients. : Takacs et al [4], +: Smith et al [5], ♦: Jourdain et al [6], −: Cannon et al [7], : Ravishankara et al [8,9],…”
