The aim of this work has been to study various muonium containing radicals not previously studied by the μSR technique with a view to determining the effect of a bound muonium atom on the radical structures as compared with their hydrogen analogues. In the first group, muonium addition to the aromatic rings of styrene, phenylacetylene and allylbenzene are compared with the more important addition to the substituent double or triple bonds. In the second group, β-muonium substituted cyclopentyl and cycloheptyl radicals are compared with their protiated versions. In the third group, radicals obtained following muonium addition to trimethylsilylethene, tri (methoxysilyl)-ethene, and 1-chloro-2, 2-dimethylethene are discussed with respect to the competition between the β-muonium atom, and β-silicon or β-chlorine substituents for control of the conformation of the radical.
