Radicals formed by gamma-radiolysis of thiaproline (thiazolidine-4-carboxylic acid) amino acid and its derivatives in a frozen acidic aqueous solution at 77 K and by subsequent warming from 95 to 200 K have been studied by electron spin resonance (ESR). The experimental parameters of radical spectra were compared with those obtained by quantum-mechanical calculations on AM1 and PM3 semiempirical levels.
