In the present work, we augment the RAS-SF methodology to include solvent polarization based on dielectric continuum theory, within the framework of the polarizable continuum model (PCM). Specifically, we introduce both equilibrium (state-relaxed) and nonequilibrium versions of the RAS-SF + PCM formalism, in order to account for differential polarization upon electronic excitation of the solute. The nonequilibrium continuum approach separates the medium's polarization response into fast (electronic) and slow (vibrational and orientational) components, then uses the solvent's optical dielectric constant (ε ∞ ) to describe the fast processes while the static dielectric constant (ε 0 ) describes the total polarization response, including both nuclear and electronic contributions. In this way, nonequilibrium PCMs describe the change in electronic polarization following a sudden change in the charge distribution of the solute, corresponding to vertical electronic excitation or vertical ionization. In contrast, the state-relaxed algorithm is targeted at equilibrium solvation where all polarization mechanisms are fully relaxed in the excited state, as appropriate for the description of emission.
