We note that the nonequilibrium correction G ptSS(1) k exceeds 1 eV for the CT state that is considered in Table I, even in nonpolar solvents. Perhaps counterintuitively, this correction is smaller in water than it is in less polar solvents. This is ultimately a consequence of the partition between "slow" and "fast" (or "inertial" and "noninertial") contributions to the solvent response, with the consequence that for a solvent like water where ε 0 ε ∞ , a much greater proportion of the solvent response is frozen upon vertical excitation. This can be understood in terms of the "Pekar factor", ε -1 ∞ -ε -1 0 , which replaces the familiar factor of 1 -ε -1 0 in the Born (or generalized Born) solvation energy expression, in cases where vertical excitation energies are involved. For example, ε -1 ∞ -ε -1 0 appears in the Marcus theory expression for the outer-sphere reorganization energy, which is the earliest version of a nonequilibrium dielectric continuum theory.
