Abstract
Solid glycine has been radiolyzed by 60Co γ-rays in vacuo at room temperature, and all the products except H2 have been measured after dissolving the irradiated samples in water. The hydrogen has been collected and measured directly from the irradiated solid samples. All products except H2 increase linearly with the dose, while H2 shows a plateau from a relatively low dose. The yields of products are as follows: G(H2)∼0.2, G(NH3)=4.8, G(CH3NH2)=0.2, G(CHOCO2H)=2.5, G(CH3CO2H)=2.3, G(CO2)∼0.2, and G(HCHO)∼0.03. The mechanisms of the primary process and the reactions to give final products have been proposed with reference to the results of the ESR studies.
