Free Radical Formation in Crystals of 2′-Deoxyguanosine 5′-Monophosphate Irradiated at 15 K: An ESR Study

Radiation-induced radicals in single crystals of 2′-deoxyguanosine 5′-monophosphate (5′-dGMP) at 15 K have been studied by electron spin resonance (ESR) spectroscopy. At low temperatures three radicals were analyzed in detail. The negatively charged π anion of the guanine base completely dominated t...
