KINETIC AND ELECTRON SPIN RESONANCE STUDIES OF THE RADIATION DECOMPOSITION CRYSTALLINE CHOLINE CHLORIDE
The free radicals that accompany the radiation decomposition of crystalline choline chloride were investigated by electron spin resonance spectroscopy. The esr spectrum obtained from the normal compound was compared to the spectra obtained from selectively-deuterated choline chlorides. The differences observed in these spectra were used to assign a structure to the radical. The radical decay reaction was found to be of 3/2 order; this indicates that the observed radicals function as a chain-initiating reactant and not as an intermediate in the radiation decomposition reaction. A kinetic mechanism for this reaction is proposed. The study of the radiation damage was extended to cover a dose range from 0.002 to 200 megarads. An uausual damage-saturation phenomenon was observed at approximately 12% decomposition. (auth)
