^aValues for neat solvents, i.e., extrapolated to C_el = 0 M (Fig. 1b) from cyclic voltammograms recorded at 0.05 and 0.1 V s⁻¹. For irreversible oxidation, the values of the half-wave potentials at various C_el are obtained from the inflection points at the rise of the anodic peaks.¹³

^bEstimated from the wavelengths, λ₀₀, where the normalized absorption and fluorescence spectra cross, ^5c,14 which is a rough approximation for the transition-dipole-moment representation.^14a
