| 英文摘要 | experimental limitations in vibrational excitation efficiency have previously hindered investigation of how vibrational energy might mediate the role of dynamical resonances in bimolecular reactions. here, we report on a high-resolution crossed-molecular-beam experiment on the vibrationally excited hd(v = 1) + f -> hf + d reaction, in which two broad peaks for backward-scattered hf(v' = 2 and 3) products clearly emerge at collision energies of 0.21 kilocalories per mole (kcal/mol) and 0.62 kcal/mol from differential cross sections measured over a range of energies. we attribute these features to excited feshbach resonances trapped in the peculiar hf(v' = 4)-d vibrationally adiabatic potential in the postbarrier region. quantum dynamics calculations on a highly accurate potential energy surface show that these resonance states correlate to the hd(v' = 1) state in the entrance channel and therefore can only be accessed by the vibrationally excited hd reagent. |
