The Study of State Resolved Reaction Dynamics of the Reaction F+C₂F₅I→IF+C₂F₅

By using the combination of laser induced fluorescence and crossed molecular beam method, the processes of the state to state reaction dynamics of the reaction F+C₂F₅I→IF+C₂F₅ were studied in detail in a wide wavelength region. The relative initial vibrational distribution of IF ground electronic state and the detail reaction rate constants were obtained from spectral analysis. The reaction mechanism was settled. A bimodel rotational distribution was discovered and the total rate constant was measured for the first time. A statistical expression of the late constant was raised, in which the zero point energy was considered, and the calculated results were in a good agreement with the experimental.
