Özet
The spectroscopic features of free radicals produced in gamma irradiation of the N-methyl-dl - alanine, N,N - dimethyl glycine hydrochloride and d - (+) - galactosamine hydrochloride were investigated at room temperature at the dose 15 kGy using EPR technique. The paramagnetic species observed in these compounds were identified as CH3CHCOOH, CHOH(CHOH)(3)NH2(CH)(2)O, and (CH3)(2)NCHCOOH.HCl, respectively. A comparison with a new paramagnetic species recently observed and characterized in irradiated amino acids indicates that the new radical presented here has a similar structure. In this paper, we have also studied the stability of these compounds at room temperature after irradiation.
