Figure summarizes the performance of SA-CASSCF, tPBE, tPBE0, L-tPBE, and L-tPBE0 on this subset of data. Expectantly, we find that SA-CASSCF (mean absolute error Figure shows how L-PDFT performs on the various types of excitations in the QUESTDB dataset (singlet-singlet, singlet-triplet, valence, etc.). We see that L-PDFT performs similarly to MC-PDFT for almost all types of excitations except for Rydberg type (Figure ), where it performs only marginally worse (difference of a several hundredths of an eV) though still much better than SA-CASSCF. These results show that the state-averaged Hamiltonian of L-PDFT (eq. 2) remains a robust method for calculating excitaiton energies on a diverse set of excited states. Even in cases where the model space is spanned by states of different spin or spatial symmetries and hence the zero-order densities are weighted averages of densities with different symmetries (for example, singlet and triplet states), L-PDFT is able to accurately calculate excitation energies. As L-PDFT is more computationally efficient than MC-PDFT in this regard (as it only requires a single DFT quadrature calculation irregardless of the number of states), it appears to be a promising method for photochemical applications of MC-PDFT in general.
