Abstract

The CH₃+HBr→CH₄+Br reaction was investigated by ab initio direct dynamics methods. The potential energy surface information required for the rate constant calculation was obtained at the PMP4//QCISD level. It was shown that for this reaction, at the reactant side, there is a hydrogen-bonded complex (HBC), and from the HBC to the products, the reaction system passes through a reactantlike transition state.
