In the following Tables, we report the vertical transition energies (in eV) obtained with the aug-cc-pVTZ basis and computed with state-averaged CASSCF, state-specific CASPT2 and CASPT3 using a level shift of \SI{0.30}{\hartree} with or without an IPEA shift of \SI{0.25}{\hartree}.
|
|
The symbol $[F]$ indicates the calculation of emission from the lowest $S_1$ geometry, i.e., the vertical fluorescence.
|
|
The composition of the active space is specified in terms of number of active orbitals per irreducible representation.
|
|
The state-averaging procedure used is also described in terms of number of states per irreducible representation.
|
|
Note that, for all calculations, the ground state is systematically included in the state averaging
|
|
procedure even if it does not belong to the same irreducible representation.
|
|
The Cartesian coordinates have been extracted from the QUEST database \cite{Veril_2021} and can be downloaded at \url{https://lcpq.github.io/QUESTDB_website}.
