Below are given the cartesian coordinates of the compounds investigated in this study.
These are provided in Angstroms (\AA ) and they have been obtained at the CC3(full)/aug-cc-pVTZ level of theory, \cite { LooSceBloGarCafJac-JCTC-18, LooBogSceCafJAc-JCTC-19} except for methylene where the FCI/TZVP geometries have been extracted from Ref.~\onlinecite { SheLeiVanSch-JCP-98} .

\section { Total energies}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
2019-05-31 11:43:26 +02:00
The exFCI total energies can be found in the { \SI } of Refs.~\onlinecite { LooSceBloGarCafJac-JCTC-18, LooBogSceCafJAc-JCTC-19} .
2019-06-25 16:35:38 +02:00
Here, we report the absolute energetic corrections for each state of each molecule obtained with the three short-range correlation functionals considered in the present study (i.e., $ \LDA $ , $ \PBEUEG $ and $ \PBEot $ ).
