The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong coupling between the spin, rotational, and orbital angular momenta. Muon spin rotation/relaxation/resonance (MuSR) does not suffer from this problem, potentially making it superior for gas phase measurements. We are attemping to demonstrate RF MuSR as a new tool for measuring organic radicals in the gas phase, opening up the possibility of measuring muon hyperfine couplings in the dilute limit and bringing the potential for final state spectroscopy and kinetics measurements on gas systems. This is a proposal to search for the radical states formed on muon implantation in ethene and isobutene using the high field spectrometer, HiFi.
