A dynamical study of the H+CH3→CH4 recombination reaction

Abstract

The Monte Carlo quasiclassical trajectory method is used to study the molecular dynamics of the H+CH3→CH4 association reaction. The bimolecular rate constant is calculated for a temperature of 300 K and compared with experimental measurements. Both the nature of the reactive trajectories and the bimolecular rate constant are very sensitive to the shape of the C–H stretching potential energy curve.
