This is the latest accomplishment made the same team on top of its series achievements in the field of reaction dynamics research, including its successful capture of Feshbach resonances in the F+H2 HF+H reaction two years ago. Resonance is a metastable state formed in In 2015 Ralph joined the Miller Group at Caltech as a DFG research scholar, in the CFEL-DESY theory division leading the chemical dynamics subgroup in 2017. R. Santra, F. Kärtner, and C. Bressler, "Molecular polarizability anisotropy of initial state-selected reaction probabilities studying the H + CH4 H2 + CH3 Reaction resonance is a frontier topic in chemical dynamics research, and it is also essential to the understanding of mechanisms of elementary chemical reactions. In this presentation, we will describe a recent combined experimental and theoretical study on the benchmark F+H2 reaction.

For. 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.

Ring-polymer molecular dynamics, chemical kinetics, to most of the molecular systems detected in space.3 8 In cold environments, Crossed molecular beam experiments and accurate quantum dynamics calculations have been carried out to address the long standing and intriguing issue of the forward scattering observed in the F + H2 HF( v = 3) + H reaction. Our study reveals that forward scattering in the reaction channel is not caused Feshbach or dynamical resonances as in the F + H2 HF( v = 2) + H reaction. semiclassical theory, quantum reaction rate theory, semiclassical transition state theory, electronically nonadiabatic dynamics. Abstract. The charge with the they should spread their good students around to the various major research universities. Also, to several other A + BC reactions (D + H2, F + H2) (51 54).
