Abstract

The formation of radical products of the radiolysis of thiosemicarbazide (hydrazine thiocarbamide) in solid phase was studied. It was shown that γ-irradiation of thiosemicarbazide at room temperature resulted in the appearance of a yellow color due to the absorption band with the maximum at 440 nm. This band and the corresponding doublet ESR signal with a hyperfine coupling constant of 2.6 mT and ag-factor value of 2.003 can be ascribed to the radicals resulting from hydrogen atom abstraction from the amide group of thiosemicarbazide. Heating the irradiated sample up to the temperatures above 400 K leads to a simultaneous decrease in intensity of the absorption band and the ESR signal.
