Vibrationally driven hydrogen abstraction from methane and its isotopologues has become nearly ubiquitous as a standard in gas phase reaction dynamics studies. To obtain a more complete view of the reaction dynamics of the hydrogen abstraction reaction of CH$_3$D with Chlorine radicals, we have studied how a dramatic change in the kinetic energy distribution of the Cl radicals affects the abstraction dynamics of our system. To this end, we have performed pump-probe experiments, exciting the 2$\nu$$_4$ CH$_3$D antisymmetric C-H stretch overtone, photolyzing Cl$_2$ with laser pulses of 309 nm, 355 nm, and 416 nm, then probing the products with (2+1) REMPI. We find both similarities and marked differences in the abstraction dynamics at the three different photolysis energies.
