ESR spectra of (A) γ-irradiated glassy sample of N3-Me-dThd (2.5 mg/ml in 7.5 M LiCl/D2O) in the presence of electron scavenger K2S2O8 at pH ca. 12 and annealed to 155 K for 15 min showing line components due to Cl2•−, and UCH2• with some T(6OH)•. (B) After annealing at 160 K for 15 min showing 70% UCH2• and 30% T(6OH)•.
