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. Abstraction rates for propane are ~0.1MHz around RT, and are therefore be accessible provided RF techniques are employed. Previous work provided good evidence for a slow reaction to form a diamagnetic product and used RF techniques to measure an average rate constant at 300K. A preliminary attempt to establish the temperature dependence of the rate was inconclusive and it is this we want to investigate in this new proposal.
