N2 - The radicals formed in the liquid and solid state radiolysis of esters of acetic acid CH3-COOR (R =-CH3, -CH2-CH3, -CH(CH3)2, -C(CH3)3) were investigated by the spin trapping technique using 2,4,6-tri-t-butylnitrosobenzene. After irradiation in the solid phase ( - 196°C), the nitroxide spin-adducts of the following radicals could be identified: H·, ·CH2-COOR, CH3-COOR·, R = alkyl. Radiolysis in the liquid state (-78°C) resulted in the nitroxide spin-adducts of alkoxy radicals. Furthermore, anilino-type spin-adducts were detected. Based on these results a mechanism for the primary reactions in the radiolysis of these esters is proposed.
