Reaction resonance is a frontier topic in chemical dynamics research,and it is also essential to the understanding of mechanisms of elementary chemical reactions.This short article describes an im- portant development in the frontier of research.Experimental evidence of reaction resonance has been detected in a full quantum state resolved reactive scattering study of the F+H2 reaction.Highly accurate full quantum scattering theoretical modeling shows that the reaction resonance is caused by two Feshbach resonance states.Further studies show that quantum interference is present between the two resonance states for the forward scattering product.This study is a significant step forward in our understanding of chemical reaction resonance in the benchmark F+H2 system.Further experimental studies on the effect of H2 rotational excitation on dynamical resonance have been carried out.Dy- namical resonance in the F+H2(j=1)reaction has also been observed.
H ++H2 反应系统上的伪古典的轨道(QCT ) 计算在新势能表面(足) 上被执行。理论计算证明前面、向后的产品的尖分发为标题反应是粗略地对称的。旋转州的分发也是的产品在一些碰撞精力决定了。在到 1.424 eV 的从 0.124 eV 的碰撞精力范围,为这个系统的不可分的生气的节 monotonically 与碰撞精力减少。有离子分子反应的试验性的结果的比较也被做,协议通常好。
