Rate constants have been measured for the reaction of the light hydrogen isotope muonium with benzene and 2,3-dimethylbutadiene-1,3 in the gas phase and in several solvents. Comparison with H atom data reveals (1) appreciable kinetic isotope effects,

Muonium-substituted free radicals are observed by muon spin rotation when positive muons are stopped in liquid substituted benzenes. From muon precession frequencies in high external magnetic fields the isotropic muon-electron hyperfine coupling cons

Hyperfine coupling constants for muonium substitited hydrazyl radicals are reported. They are compared with the existing data for the hydrogen analogs. The influence of the temperature and the solvent are given.

Muonium-substituted free radicals are observed by muon spin rotation when positive muons are stopped in liquid methyl, and fluorine-substituted benzenes. From muon precession frequencies in high external magnetic fields the isotropic muon-electron hy

Avoided-level-crossing resonances from isotropic muonium centres interacting with neighbouring nuclear spins in powdered CuCl are reported. The prominent resonances have a complex multiline structure and are strongly temperature-dependent. In additio

The distribution of muon polarization between different radicals observed in neat p-di-fluorobenzene, aniline and bromobenzene and their binary mixtures with benzene has been measured and is interpreted in terms of relative rate constants for Mu addi

The radiolysis of aqueous solutions of Cu EDTA 2- in the presence of a number of alcohols was studied by the pulse-radiolysis technique. After the reduction of Cu EDTA 2− by e − aq a complex is formed between Cu (I) EDTA 3− and the radicals res

Observation of substituted cyclohexadienyl type radicals by muon spin rotation in substituted benzene at different concentrations of added p-benzoquinone or duroquinone allows a selective determination of rate constants for the reaction of the radica
