英文摘要The effects of CH stretching excitation on the reactivity of the F + CHD3 -> HF + CD3 reaction were studied experimentally using crossed-beam and time-sliced velocity map imaging techniques over the collision energy range of 1.21 to 9.00 kcal mol(-1). The experimental results showed that the CH stretching excitation promoted its cleavage and enhanced the title reaction at low collision energies. This enhancement dropped with an increase of the collision energy. And at high collision energies, CH stretching excitation appeared to lower the reactivity of the above reaction, in contrast to the case at low collision energies. This decreasing trend in the enhancement of reactivity was in agreement with previous theoretical studies. The vibrationally excited reaction was further compared with the ground-state reaction at a same total reagent energy of 9.80 kcal mol(-1), and similar reactivities were derived.
