Before introducing the definition of sobEDAw, one should first pay great attention to the concept of "dispersion interaction". Contribution of dispersion interaction to total intermolecular interaction can only be separated from other effects ambiguously in the case that there is no overlap between electron density of the interacting molecules, and it is well-known that dispersion effect sources from long-range Coulomb correlation between the electrons in the respective molecules. However, chemists are mostly interested in molecular complexes in equilibrium configuration. In this case intermolecular electron density overlap is never negligible, not only long-range but also middle-range Coulomb correlation exist, and hence there is no unique way to divide the dispersion interaction from the total interaction. The dispersion term defined by SAPT method fully represents intermolecular Coulomb correlation, the middle-range part is also included, so it may be more appropriate to be referred to as "dispersion-like"
