  1. Hait and Head-Gordon, JCTC 2018


NIST Computational Chemistry Database for most molecules,
MP2/cc-pVTZ for BH2F and BH2Cl,
taken from NCCE31 and TA13 data sets for non-covalent complexes

Reference energies

All electron, unrestricted composite CCSD(T)/CBS dipole moments calculated as
HF/aug-cc-pCV5Z + dCCSD(T) extrapolated from:
aug-cc-pCV5Z and aug-cc-pCVQZ for smaller systems
aug-cc-pCVQZ and aug-cc-pCVTZ for larger ones


The data set is divided into following groups (by spin treatment (spin-polarized group includes also singlet systems with broken spin symmetry)):
