  • The crossed beams scattering dynamics of the F+HD→DF+H reaction have been studied at collision energies ranging from 8.19 kJ/mol to 18.98 kJ/mol using the high resolution H-atom Rydberg tagging time-of-flight method. Product rotational state-resolved differen-tial cross sections have been measured. Most of the DF products are backward scattered at low collision energies and then gradually shift to the sideway as the collision energy in-creases. In addition to the backward and sideway scatterings, we have also observed the DF(v′=4) product in the forward direction for the first time for this reaction. The forward scattering DF(v′=4) product also increases with the collision energy. Angular and collision energy dependence of the product energy disposals in different degrees of freedom have been determined. Collision energy dependence of the vibrational branching ratios has also been examined. Possible dynamical origins of the forward scattering DF(v′=4) products were discussed.

Abstract: The crossed beams scattering dynamics of the F+HD→DF+H reaction have been studied at collision energies ranging from 8.19 kJ/mol to 18.98 kJ/mol using the high resolution H-atom Rydberg tagging time-of-flight method. Product rotational state-resolved differen-tial cross sections have been measured. Most of the DF products are backward scattered at low collision energies and then gradually shift to the sideway as the collision energy in-creases. In addition to the backward and sideway scatterings, we have also observed the DF(v′=4) product in the forward direction for the first time for this reaction. The forward scattering DF(v′=4) product also increases with the collision energy. Angular and collision energy dependence of the product energy disposals in different degrees of freedom have been determined. Collision energy dependence of the vibrational branching ratios has also been examined. Possible dynamical origins of the forward scattering DF(v′=4) products were discussed.
