As already mentioned above, in all four systems, the vertical energy gap distributions are Gaussian (Figures and). Consequently, the free energy curves (Figures and) are parabolic. Both of these outcomes are consistent with the validity of Marcus Theory. In addition, the very small differences seen in the respective VIE vs VEA standard deviations both in absolute values (0.24 eV vs 0.24 eV for native region 1, 0.24 eV vs 0.26 eV for native region 2, and 0.23 eV vs 0.27 eV for both 8oxoG-containing systems) and relative with respect to the average values (3.1% vs 4.1% for the native region 1, 3.0% vs 4.5% for the native region 2, and 3.3% vs 5.9% for both 8oxoG-containing systems) are also very well in line with the Marcus model.
