Abstract (EN):
Muonium substituted free radicals are observed by muon spin rotation when positive muons are stopped in liquid olefins and dienes. From muon precession the isotropic muon-electron hyperfine coupling constants have been determined for 44 radicals and analyzed to yield the radical structures. Primary, from mono-olefins, and mainly allylic radicals from conjugated dienes. They are formed by addition of the light hydrogen isotope muonium (Mu = ¿ + the relations between coupling constants and radical structures follow the principles known for the analogous H substituted radicals. Further, the regi to that of H atoms. © 1982.
