Abstract
An overview is presented of the way various spectroscopic/radioisotopic-labelling methods (MuSR), in which free radicals are labelled with the light hydrogen radioisotope muonium, may be employed in the study of free radical reaction kinetics and dynamics. Specifically considered are: the reaction rates of thiyl radicals and related species in relation to biological membrane damage; the dynamics of radicals sorbed in solid catalysts and in activated carbons and other porous particulate materials of environmental significance; reacting gas-phase systems; mechanisms for the formation of muon (muonium) labelled radicals, and the study of radical stabilisation and reactivity.
