The dynamics of the F + CH4 → HF + CH3 and F + CD4 → DF + CD3 reactions have been investigated using classical trajectory calculations at the MP2/cc-pvdz level of theory. The trajectories were calculated directly from electronic structure computations, and a Hessian based method with updating was used to integrate the trajectories. Using this method, product rovibrational populations and internal energy distributions were obtained for the F + CH4 and F + CD4 reactions. The theoretical results were compared with the available experimental data and previous calculations results. The state distributions of the reaction F + CH4 in these calculations are in reasonable agreement with the experimental results, which indicates that the experimental behavior of the reaction could be well reproduced by the direct classical trajectory calculations at MP2/cc-pvdz level. As such, the product rovibrational populations and internal energy distributions for the reaction F + CD4 were predicted. The same degree of agreement between theory and experiment as the F + CH4 reaction is expected. |
