CH Stretching Excitation Steers the F Atom to the CD Bond in the F + CHD_3 Reaction

摘要

The investigation of the details of chemical reactivity is an active area at the heart of chemistry. One well-established probe of reactivity is the dependence of aspects of the reaction (e.g., rate, branching ratios, final-state distributions, etc.) on the vibrational excitation of the reactants. In general, such excitation activates the reaction and, more specifically, the reaction pathway associated with the bond that is excited. Thus, it was quite surprising that vibrational excitation of the CH stretch in the F + CHD_3 reaction, which was recently studied by Liu and co-workers in a crossed molecular beam experiment, suppressed the HF + CD_3 channel.
