Unimolecular reactions of vibrationally excited C[F.sub.2]ClCHFC[H.sub.3] and C[F.sub.2]ClCHFC[D.sub.3]: Evidence for the 1,2-FCl interchange pathways

The chemical activation techniques coupled with electronic structure calculations were used to investigate the unimolecular reactions of a series of chlorofluoropropane molecules. Fully halogenated fluorochloroethanes and propanes seem to have high threshold energies for ClF interchange, and other decomposition pathways are favored over ClF interchange.
