چکیده انگلیسی


• The irradiation effects on three succinic acid derivatives have been investigated by EPR spectroscopy.
• The radicals produced in the succinic acid derivatives were attributed to alkyl type radicals.
• The EPR parameters of the radicals formed in the samples after irradiation were determined.

2,2-dimethyl succinic acid, 2,3-dimethyl succinic acid and monomethyl succinate were exposed to gamma radiation in the form of powder. EPR measurements were carried out to investigate the free radicals produced in all of them, following irradiation. Three of the radical species formed after irradiation were identified and spectroscopic parameters were discussed thereafter. The radical species were attributed to the ĊHCH2, HOOCCH(CH3)2ĊCOOH and H3COOCCH2ĊHCOOH radicals, respectively. The hyperfine splitting constants for all radicals were confirmed by the simulation of the experimental spectra. The radiation sensitivity of the samples was mainly attributed to the EPR line properties of stable radicals.
