Boron Atom Reactions with the Epoxides: Vibrational Distributions in the Product BO(A2II) State

Article abstract of DOI:10.1021/j150664a019

The results of chemiluminescence studies are reported for the reactions of boron atoms with ethylene oxide, propylene oxide, butylene oxide, diepoxybutane, cyclopentene oxide, cyclohexene oxide, 3-vinylcyclohexene oxide, and styrene oxide.The experiments were done under single-collision conditions in a beam-gas apparatus.The nascent vibrational distributions in the electronically excited product BO(A²II) were determined.These distributions are well fitted by a statistical model which assumes that only those modes of the polyatomic product are excited which correspond to the conformation change in the transition from the reacting epoxide to the alkene product.Absolute cross sections for the production of the A²II state of BO are also reported.
