Initial vibrational product distributions have been obtained for the thermal proton abstraction reactions, Cl−+HBr→HCl(v=0,1)+Br− and Cl−+HI→HCl(v=0,1,2)+I−. The experimental method utilizes detection of infrared chemiluminescence from the products of the ion–molecule reactions in a flowing afterglow. A detailed description of the apparatus design and characteristics is given. The initial relative HCl product vibrational distribution for the reaction Cl−+HI was determined to be Nv=1=1.0, Nv=2=0.85±0.05. The ratio of the total emission from Cl−+HBr to that from Cl−+HI was measured to be 39±2%. The results suggest substantial disposal of energy into product vibrations in these ion–molecule reactions.
