(A) ESR spectrum of one-electron oxidized dGpdG (1 mg/ml) by Cl2•− attack in the presence of K2S2O8 (5 mg/ml) as an electron scavenger in 7.5 M LiCl glass / D2O. (B) Spectrum found after visible photo-excitation the sample in A for 90 min at 143 K. Nearly complete conversion of G•+ to sugar radicals is found. Analyses shows three radicals: C5′• (prominent doublet at the centre), C1′• (prominent quartet) and a very small amount of C3′• visible in the wings. All spectra were recorded at 77 K.
