Deuterium Isotope Effect in Halogen Atom Reactions with Methane and Perdeuteriomethane at Energies above Thermal Thresholds

Published

Journal Article

The origin of the isotope effect in the reaction of recoil chlorine atoms with methane and perdeuteriomethane was determined by diluting the systems with inert moderator to establish a unique steady-state collision distribution. The ratio of product yields from the hydrogenated system to those from the deuterated system as a function of moderator suggests that the isotope effect is primarily reactive in nature. The average probability of forming CH3Cl upon collision compared with CD3Cl is about 1.8 and that of forming CH2Cl compared with CD2Cl is about 1.6 in their respective systems. © 1973, American Chemical Society.
