ESR study of chlorine containing radicals in x-irradiated N-chlorosuccinimide at 77 K
Three different radicals were identified by ESR studies in x-irradiated single crystals of N-chlorosuccinimide; radicals I and II, stable at 77 K and radical III, stable at 240 K. Radical I was identified as the previously reported sigma anion radical, >N-Cl/sup -/. Radical II was found difficult to saturate at 200 mW and was assigned to a chlorine atom interacting weakly with a nearby nitrogen with g/sub z/=2.008, g/sub x/=2.120, and g/sub y/=2.126. The chlorine and nitrogen hyperfine couplings were found to be A/sub z/=116.0, A/sub x/=6.4, A/sub y/=4.2 G, and A/sub z/=8.4, A/sub x/=4.7 and A/sub y/=4.4 G, respectively. At 240 K, radical III was formed by the abstraction of a ring proton from a neighboring N-chlorosuccinimide molecule when radical I decayed.
