Abstract : Fluorine atoms react with methane at low collision energies according to the chemical-laser reaction; F+CH4 to HF(*)+CH3. At somewhat higher energies (1-1.5 eV) the reaction F+CH4 to FCH3+H is possible. The fluorine-methane system is considered in this analysis as a three-particle system consisting of a fluorine atom, a hydrogen atom, and a methyl radical. The use of a three-parameter London-Eyring-Polyanyi-Sato (LEPS) potential, energy surface, in conjunction with Monte Carlo trajectory calculations, has made it possible to reproduce theoretically the results of several experiments and to make a prediction for another.
