Excellent correlation is found between standard QTAIM metrics and An-N bond lengths, and with N-N bond lengths and vibrational frequencies, but much poorer correlations exist with An-N and An-O interaction energies. Superior correlations are found between interaction energies and the change in the QTAIM charge on compound formation.
