Notes:
Activation parameters for the surface dynamics of radicals produced by the addition of muonium to the unsaturated organic substrates cyclopentene, benzene, tetramethylethylene [2,3-dimethylbut-2-ene (TME)] and 2,3-dimethylbuta-1,3-diene (DMBD) adsorbed in the zeolites Na-mordenite and NaX and on silica have been determined by means of transverse-field muon spin rotation spectroscopy. This allows the study of the influence of adsorption by the different surfaces on these parameters. The temperature dependences of the muon hyperfine couplings were also studied and were found to be highly sensitive to the type of catalyst, and so to the nature of the adsorption site.
