Kinetics of Hydrogen Abstraction in Alkanes by Mu Reactivity studied by RF Resonance

Abstract: Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit study for their relevance to current environmental concerns. The lower mass alkanes also provide important test cases for H-atom reaction rate theory for polyatomic systems. Due to its remarkably light muon mass, studies of Mu reactivity provide unique tests of quantum mass effects in rate theory. RF techniques provide a unique method for studying slow reaction rates, and have been applied to measure an average rate constant for propane at 300K. Results suggest a dominant contribution to the Mu reaction from quantum tunnelling, and it is this we want to investigate in this new proposal through variable temperature measurments on both propane and butane.
