Variable-temperature EPR was used to investigate reactions of olefin radical cations generated radiolytically in nonacidic and acidic ZSM-5 zeolites.The olefin radical cations undergo isomerization reactions even at 4K.Radical cation reactions are presumably driven by the exothermicity of charge transfer, which is not efficiently quenched by the vibrational modes of the zeolite lattice.The observation of H-addition type radicals indicates Bronsted acid-catalyzed rearrangements prior to irradiation on the more acidic zeolites.
