In contrast, however, augmenting χ 0 with the frequency-dependent solvent polarizability significantly changes the predicted G 0 W 0 and GW 0 eigenvalues. The GW 0 @GGA+SaLSA+χ lq method significantly lowers the GGA+SaLSA HOMO levels (median decrease of 4.30 eV). Unlike in vacuum or when using only the SaLSA FIG. . Summary of predicted HOMO-LUMO gaps of small molecules using GGA in vacuum (black), GGA plus SaLSA implicit solvation (red), GW0 with GGA wavefunctions in vacuum (gold), GW0 with GGA plus SaLSA implicit solvation wavefunctions (blue), and GW0 with GGA plus SaLSA implicit solvation wavefunctions and liquid polarizability (purple). The dotted lines are included as guides to the eye.
