Energy disposal by F atom abstraction reactions: HF vibrational–rotational distributions from F+HBr and HI

HF infrared chemiluminescence from the reactions of F atoms with HCl, HBr, and HI was used to assign vibrational–rotational populations of the HF product. Experiments were done in both a cold‐wall, arrested vibrational–rotational relaxation apparatus and in a fast‐flow, arrested vibrational relaxation apparatus. Since the total HF formation rate constants are known for these reactions, absolute 300 K rate constants for formation of HFvJ are established. The mean vibrational energy disposal to HF including estimates for HF (v=0) is
