Two types of radiation induced primary radicals have been detected. One of them (R-1) occurs by hydrogen abstraction from methylene group next to the carbonyl group, while the other (R-2) by hydrogen abstraction from methylene group next to amide group. R1 is observed to be converted into an alkoxy radical (R-3). Decay kinetics of the radicals in nitrogen was also examined and decay mechanisms have been proposed for each radical.
