Radical cations were produced by y-irradiation of solutes in zeolites at 77 K. The radical cation of tetramethylethylene (TME) was examined by EPR in a variety of zeolites at different temperatures and loading. The TME monomer radical cation, the TME dimer radical cation and the neutral radical form

Hexamethylethane (HME) and trimethylbutane (TMB) radical cations produced in ZSM-5 zeolite by y radiolysis undergo an elimination process followed by an ion-molecule reaction. The tetramethylethylene radical cation intermediate formed by CH, elimination from TMB+' is observed directly in the tempera
