We examine the effect varying the collision energy has on the bimolecular reaction of CH₃D and chlorine. A Raman shifting cell pumped at 355 nm and filled with either hygrogen or methane gas provides, in discrete steps, light to photolyze Cl₂. This imparts bewteen 600 and 2000 cm^-1 of collision energy to our system. By also adding C-H vibrational overtone excitation, around 6000 cm^-1, we can compare to previous, fixed-photolysis energy studies from our reseach group. We seek to elucidate the role translational energy (collision energy) plays in this reactive system.
