EPR measurements of HFS of nuclei 1H, 2D in spectra of quartz glasses and 29Si in spectra of high‐silicate glasses have been made and analysed. A stochastic model for the γ‐radiation‐induced paramagnetic centres are suggested. Calculations of the electronic structure of the unit AB4 have been carried out and a correlation diagram between the orbitals possible for tetrahedral (Td) and pyramidal (C3v) configurations has been obtained. This enables one to make comments on the EPR spectra of the units SiO43− and ROSiO32−.
