Abstract

Muonium atoms produced in water react with thioacetamide (CH3CSNH2) to form a sulphur-centred (thiyl) free radical whose level-crossing-resonance from the CH3-protons has been detected and analysed. Its amplitude increases with concentration below approximately 10(2) M but decrease at higher concentrations with a concommitant increase in linewidth. This is interpreted as indicating overlap with paramagnetic species from the muon track. It starts when the track is a few nanoseconds old.
