Moving from ECIS+FDA to ECISD+FDA, the RMSD of energies drop by about a third for both triplets and singlets (to 60 and 90 meV, respectively). It appears that the excitonic doubles correct the descriptions of the dominantly LE states. The energetic ordering and degeneracy patterns are preserved, and the oscillator strengths are not affected by the addition of the excitonic doubles (compare ECIS+FDA and ECISD+FDA in Table ).
