State-to-State Dynamical Research in the F+H2 Reaction by Zefeng Ren
By Zefeng Ren
This thesis addresses very important and in addition demanding concerns within the learn of chemical response dynamics of F+H2 method. One is to probe the response resonance and the opposite is to figure out the level of the breakdown of the Born-Oppenheimer approximation (BOA) experimentally. the writer introduces a cutting-edge crossed molecular beam-scattering gear utilizing a hydrogen atom Rydberg "tagging" time-of-flight procedure, and provides thorough state-to-state experimental experiences to handle the above concerns. the writer additionally describes the statement of the Feshbach resonance within the F+H2 response, an exact dimension of the differential pass part within the F+HD response, and validation of a brand new actual power strength floor with spectroscopic accuracy. furthermore, the writer determines the reactivity ratio among the floor nation F(2P3/2) and the excited nation F*(2P1/2) within the F+D2 response, and exploits the breakdown of BOA within the low collision energy.
