15 Natural orbital occupation number (NOON) analysis In order to analyze the nature of electron correlation captured by the CASSCF wavefunction for the 1 L a ( 1 B 3g ) and 1 L b ( 1 B 2g ) states, we examine the differences in electron occupancies for orbitals between the CASSCF and mean-field (MF) wavefunctions. The deviation from the MF description is associated with the effect of electron correlation. To measure the relative degree of the correlation effect of each excited state compared to that of the ( 1 A g ), we evaluated the following indexes defined as Δ I ( 1 L a ) = {n I ( 1 L a ) n I ( 1 A g ) } { n I MF ( 1 L a ) n I MF ( 1 A g )}, (S1a) Δ I ( 1 L b ) = {n I ( 1 L b ) n I ( 1 A g ) } { n I MF ( 1 L b ) n I MF ( 1 A g )}, (S1b) where n I (X) and n I MF (X) refer to the occupancies of the orbital I of the state X for the CASSCF and MF wavefunctions, respectively. Eqs (S1a) and (S1b) gauge the degree of the role of orbital I in describing the electron correlation that affects the change in occupancy caused by the excitation. The values of n I MF (X) are shown in Table S6. The values of Δ I ( 1 L a ) (Eq. (S1a)) and Δ I ( 1 L b ) (Eq. (S1b)) obtained using the occupation numbers provided in Tables S1 S3 and S6 are shown in Table S7 for the CASSCF wavefunctions with CAS(8πe, 8πo), CAS(10πe, 10πo), CAS(12πe, 12πo), and CAS(20πe, 20πo).
