Özet
The spectroscopic parameters of the paramagnetic species produced in gamma-irradiated L-citrulline, alpha-methyl-m-serine, 3-fluoro-DL-valine and N-acetyl-L-cysteine were investigated at room temperature at a dose of 20 kGy by using EPR technique. The paramagnetic species were attributed to NH2CONH(CH2)(3)CNH2COOH, HOCH2CCH3COOH and HOCHCCH3NH2COOH, CH3CH3CCHNH2COOH and SHCH(2)GNHCOCH(3)COOH radicals, respectively. EPR data of the unpaired electron with the environmental protons and N-14 nucleus were used to characterize the contributing radicals produced in gamma irradiated compounds. In this paper, the stability of these compounds at room temperature after irradiation was also studied. (C) 2016 Elsevier B.V. All rights reserved.
