Summary

Extended electron distributions (XEDs) have been used to simulate the formation of complexes by intermolecular interaction via: (i) aromatic stacking; and (ii) hydrogen bonding. The results qualitatively reproduce experimental observations. In contrast, atom-centred partial charges fail to reproduce highly hydrogen-bonded systems, but make little difference in cases where interactions are driven largely by van der Waals forces. The dielectric constant used in the Coulombic term has been shown to be significant in defining the type and properties of these interactions when XEDs are employed. Some consideration has been given to solvation and entropy effects.
