Radiation effect studies in single crystal of Trifluoroacetyl-alpha-Aminoisobutyric acid

Abstract

In this study, electron paramagnetic resonance of -irradiated single crystals of N-Trifluoroacetyl--amino isobutyric acid (F3Ac-Aib-OH) was investigated at room temperature and analyzed for different orientations of the crystal in the magnetic field. The paramagnetic species in N-Trifluoroacetyl--aminoisobutyric acid was attributed to the CF2-R radical (R= CONHC(CH3)COOH). Hyperfine coupling constants and g value were also determined. In addition, the single crystal of F3Ac-Aib-OH was UV-irradiated and paramagnetic species formed was studied at room temperature. The effects of gamma irradiation on fluoroamino acid and stability were discussed.
