The paramagnetic species were attributed to the -CHCHNH-, -CH2CH2CH- and -CH-, -CHCH2N- and -CH-, and -NCCH2- radicals, respectively. The results were observed as being in good conformity with the literature. The spectra of these compounds were computer simulated. Furthermore, the EPR parameters of the radicals formed by (SIC)-irradiation in the samples were determined. (C) 2018 Elsevier B.V.
