Abstract: Gamma-irradiated sulfanilic acid (C6H7NO3S) single crystals were analyzed by electron paramagnetic resonance spectroscopy at 120 K temperature. The irradiation was carried out at room temperature using a 60Co-gamma source. EPR spectra of gamma-irradiated sulfanilic acid single crystals were obtained by rotating the magnetic field for three different orientations of the crystal. The paramagnetic center formed in the gamma-irradiated sulfanilic acid single crystal was determined by examining of the EPR spectra. The EPR spectra of this compound have been found to be temperature independent. The principal values of the hyperfine structure constants of the unpaired electron, and the principal values of the g-tensor and direction cosines of the radiation damage centers are calculated. The values were compared with those in the literature, and the results were found to be consistent. © 2019 Polish Academy of Sciences. All rights reserved.
