The method introduced in the work builds upon the RAS-SF approach for CT states, introducing a PCM framework for solvation effects. The RAS-SF formalism is briefly reviewed in Section II A, following which we introduce the state-specific equilibrium and nonequilibrium solvation theories in Sections II B and II C, respectively. The nonequilibrium version is built upon a perturbative framework introduced previously. Section II D describes how the PCM theory is integrated with the RAS-SF approach to computing the wave function.
