Full quantum state resolved scattering of the F atom reaction with H(2)(j=0) and H(2)(j=1) was investigated at the collision energies of 0.19 and 0.56 kcalmol. Dramatic difference between the dynamics for the F+H(2)(j=0,1) reactions at both collision energies have been observed. Forward scattering HF(v(')=2) products have been observed unambiguously for the F+H(2)(j=1) reaction at low collision energies, which was attributed to the Feshbach resonances. This study provides a unique case of reaction resonances involving a rotationally excited reagent.
在0.19和0.56千卡/摩尔的碰撞能量下，研究了F原子与H₂（j = 0）和H₂（j = 1）反应的全量子态分辨散射。在这两种碰撞能量下，均观察到F + H₂（j = 0,1）反应动力学之间的显著差异。在低碰撞能量下，对于F + H₂（j = 1）反应，已明确观察到向前散射的HF（v' = 2）产物，这归因于费什巴赫共振。该研究提供了一个涉及旋转激发反应物的反应共振的独特案例。
