Binding energies of first row diatomics in the light of the interacting quantum atoms approach

The straightforward application of the interacting quantum atoms (IQA)/quantum theory of atoms in molecules (QTAM) approach to the decomposition of the binding energy of first row diatomics into self-and interaction components has provided a complementary new way to rationalize the experimental facts. The ability of the IQA approach to generate sensible atomic self-energies that hide all the important cancellations of the usual energetic terms of quantum chemistry might be used to introduce new complementary ways of understanding the chemical phenomena.
