State-to-State Dynamical Research in the F+H2 Reaction System [Paperback]

This thesis addresses two important and also challenging issues in the research of chemical reaction dynamics of?F+H2 system. One is to probe the reaction resonance and the other is to determine the extent of the breakdown of the Born-Oppenheimer approximation (BOA)?experimentally. The author introduces a state-of-the-art crossed molecular beam-scattering apparatus?using a?hydrogen atom?Rydberg tagging time-of-flight method, and presents thorough state-to-state experimental studies to address?the?above issues. The author also describes the observation of the?Feshbach resonance in?the?F+H2 reaction,?a?precise measurement of the differential cross section in?the?F+HD reaction, and validation of a new accurate potential energy surface with spectroscopic accuracy. Moreover, the author determines the reactivity ratio between the ground state F(2P3/2) and the excited state F*(2P1/2) in?the?F+D2 reaction, and exploits the breakdown of BOA in the low collision energy.

This book introduces a new crossed molecular beam scattering apparatus with a high time-of-flight resolution. It describes the observation of Feshbach resonances in F+H2 reaction and presents the measurement of nonadiabatic effects in F+D2 reaction.Introduction.- Hydrogen Atom Rydberg Tagging Time-of-Flight Crossed Molecular Beam Apparatus.- Dynamical Resonances in F+H₂ Reactions.- The Non-Adiabatic Effects in F(²P)+D₂?DF+D.
