摘要:
The vibrational enhancement factor in the Cl + CHD3(v(1) = 1) reaction is revisited over the collisional energy range of 2-5.9 kcal mol(-l). Contrary to the previous results obtained by probing the low-vertical bar N, K > states of CD3(v = 0) products, CH stretching excitation becomes more efficacious than the same amount of translational energy in promoting the HCl(v) + CD3(v = 0) product pairs when all-vertical bar N, K > states are probed. Whereas the new vibrational enhancement factors, which are three to four times larger than the previous report, agree reasonably well with a recent reduced-dimensionality quantum dynamics calculation, a cautious note is made on the different initial vertical bar JK > rotational selections of the CHD3 reactants in the present theory-experiment comparison.
