摘要: Reaction resonance is a frontier topic in chemical dynamics research, and it is aiso essential to the understanding of mechanisms of elementary chemical reactions. In this presentation, we all describe a recent combined experimental and theroetical study on the benchmark F+H2 reaction. Experimental evidence of reaction resonance has been detected in a full quamtumstate resolved reactive scattering study of the F+H2 reaction. Highly accurate full quantum scattering theroetical modeling shows that the reaction resonance is caused by two reaction resonance states. Further studies show that quantum interference is present between the two reaction resonance states for the forward scattering product. This study is a significant step forward in our understanding of chemical reaction resonances in the benchmark F+H2 system. Further experimental studies on the effect of H2 rotational excitation on dynamical resonances were carried out. Dynamical resonances on the F+H2(j=1)reaction have also been observed. A more recent study on the F+HD system has also been carried out.The isotope substitutionactually provides an extremely senstive probe to the reaction resonance potential surface in this important system.
