We report a study of the reaction dynamics of the H + CDCl3 --> HD(ups
ilon'j') + CCl3 reaction with the CDCl3 reactant prepared in the nu(1)
C-D stretch upsilon ''=1 excited state. Stimulated Raman excitation i
s used to prepare the CDCl3(upsilon ''=1) reactant and coherent anti-S
tokes Raman scattering is used to detect the HD(upsilon'j') product, u
nder effectively single-collision conditions at a relative energy of 1
.6 eV. Even though the vibrational excitation energy of the reactant (
0.28 eV) is small compared to the collision energy, which greatly exce
eds the reaction barrier height, the vibrational excitation of the rea
ctant increases the reaction cross section by a factor of 1.66 +/- 0.1
5. Despite this, none of the energy added by the reactant vibrational
excitation appears as HD product vibration or rotation. All of it goes
into product translation and/or CCl3 internal energy.
