The ground‐state reaction of Cl + CHD 3 was studied with joint experimental and theoretical efforts. Experiments were performed under crossed‐beam conditions using a time‐sliced velocity imaging detection method. By taking the images over the energy range of chemical significance—from threshold to about 9 kcal/mol—the reactive excitation functions as well as the dependence of product angular distributions and of the energy disposal on initial collision energies were obtained for both isotopic product channels. Theoretically, reduced dimensionality quantum dynamics calculations were performed for the HCl + CD 3 channel, and the results are in excellent agreement with experimental findings. Comparisons with previously reported results on Cl + CH 4 /CD 4 , both experimental and theoretical, were also made to gain deeper insights into the dynamics of this benchmark atom + polyatomic reaction.
