Title: ESR study of stable radicals in an irradiated single crystal of deoxyguanosine 5'-phosphate (Na salt)

Abstract

Three different radical species have been identified in an irradiated single crystal of deoxyguanosine 5'-phosphate at room temperature. The dominating species is a hydrogen-addition radical with spectroscopic characteristics similar to those of the N(7)-protonated H-addition radical in guanine/sup ./HCl. The well-resolved quartet ESR pattern is believed to belong to a radical in the sugar moiety formed by breakage of the furanose ring in the same manner as that reported earlier for deoxycytidine 5'-phosphate. The third species present is either a protonated anion or a deprotonated cation located in this six-member ring of the guanine base.
