ESR spectra of one-electron oxidized d[TGCGCGCA]2 and model compounds in glassy 7.5 M LiCl solutions at pH ca. 9. (A) ESR spectrum of G(N2-H)• obtained from d[TGCGCGCA]2 in H2O (blue) formed after annealing to ca. 173 K. The authentic G(N2-H)• spectrum (green) from 1-Me-dGuo and the authentic G(N1-H)• spectrum (red) obtained from dGuo are superimposed on it. The wings show the Azz component of the exchangeable N2-H coupling in ds oligomer in H2O. (B) Comparison of the spectrum of one-electron oxidized d[TGCGCGCA] in H2O from A (blue) with that found in D2O (black) for an otherwise identical sample. The Azz component of the remaining N2-H proton hyperfine coupling of G(N2-H)• is clearly visible in the wings spectrum (blue) in Figure (B). All ESR spectra were recorded at 77 K.
