| 英文摘要 | most studies of the impact of vibrational excitation on molecular reactivity have focused on reactions with a late barrier (that is, a transition state resembling the products). for an early barrier reaction, conventional wisdom predicts that a reactant's vibration should not couple efficiently to the reaction coordinate and thus should have little impact on the outcome. we report here an in-depth experimental study of the reactivity effects exerted by reactant c-h stretching excitation in a prototypical early-barrier reaction, f + chd3. rather counterintuitively, we find that the vibration hinders the overall reaction rate, inhibits scission of the excited bond itself (favoring the df + chd2 product channel), and influences the coproduct vibrational distribution despite being conserved in the chd2 product. the results highlight substantial gaps in our predictive framework for state-selective polyatomic reactivity. |
