Here we show that L-PDFT yields similar PES topology to CMS-PDFT for a variety of challenging cases including phenol, methylamine, and the spiro cation and, it does not have the same intrinsic limitations of CMS-PDFT for linear systems with degenerate 1 ∆ u states (see Section 4.6). Additionally, we compute the vertical excitation energy for a small test set of representative organic chromophores and find that L-PDFT is more accurate than MC-PDFT and CMS-PDFT.
