Description

Investigated are ESR spectra and stability of free radicals forming as a result of γ-irradiation at -196 deg of triethylbenzol, diethyl spirit of dimethylmalon acid and tret butylbenzol, sorbed by NaX and CaX zeolites at room and increased temperatures. Anomalously high stability is characteristic only of radicals formed of γ-irradiated molecules, traversing close to the diameter of zeolite entry windows. The obtained data testifies to the effect that radiospectroscopy in combination with radiation effect on the adsorbed substances can successfully be used as the most sensitive method for porous structure characteristic of mineral adsorbents, in particular, for direct investigation of activized physical adsorption processes
