We next compare RAS-SF + ptSS-PCM results to the corresponding calculation at the CIS level, which will illustrate the ease of reaching target states with the RAS-SF procedure. Table shows the results for the pentacene dimer model in Fig. (b), in two different solvents. In cyclohexane, we observe a correspondence between the RAS-SF states LCT1 (triplet) and LCT2 (singlet) and the 37th and 38th excited states obtained from the CIS calculation. Comparing excitation energies, the RAS-SF and the CIS results agree to within 0.04 eV and the dipole moments agree to within 0.5 D. A similar correspondence is observed between the RAS-SF states RCT1 and RCT2 and the 39th and 40th excited states obtained from the CIS calculation. The principle pair of natural transition orbitals (NTOs) for states 37 and 39 are plotted in Fig. , from the CIS calculation, which confirms the CT character of the states in question. (The RAS-SF states have CT character by construction.) While the excitation energies are similar, indicative of the lack of significant dynamical correlation in the RAS-SF wave function, the CIS approach necessitates calculation of a large number of excited states, which must then be analyzed in terms of orbitals and amplitudes in order to deduce which states possess CT character. With RAS-SF, on the other hand, one may target the CT states directly (essentially by fiat), so that these emerge as the lowest eigenvalues of the CT block of the Hamiltonian. Steady state absorption measurements performed on the intramolecular singlet fission chromophore in Fig. (a) indicate a red shift in the absorption maxima as solvent polarity increases, which was taken as evidence that the excited state is more polar than the ground state. We observe a similar pattern for the unlinked dimer model, as discussed above, with a decrease in the excitation energy as a function of increasing solvent polarity, although such a shift is observed in both the LE and the CT states. latter calculations were performed in vacuo so the same is true for the RAS-SF calculations in Table . Both sets of calculations reveal four closely-spaced excited states of alternating multiplicity (singlet and triplet), with significant CT character as indicated by excited-state dipole moments µ ≈ 65 D. This comparison suggests at least a qualitative correspondence between the two levels of theory, even if the gas-phase excitation energies are rather different. In Ref. 61, the effects of solvent polarity were investigated by comparing excitation energies in vacuum to those computed in benzonitrile, using a SCRF model
