B3LYP-D3(BJ)/def2-QZVP minimum + scaling of closest contact distance along interaction coordinate

Reference energies

First point and equlibrium geometry - composite CCSD(T)/CBS, CP-corrected, Helgaker extrapolation, frozen core:
dMP2/aug-cc-pVQZ -> aug-cc-pV5Z
Other points: same scheme with HF/aug-cc-pVQZ + dMP2/aug-cc-pVTZ -> aug-cc-pVQZ + dCCSD(T)/aug-cc-PVDZ,
rescaled to the higher level


The data set is divided into following groups (by the type of the interaction):

Alternative reference data
