ABSTRACT Along the historical background of science, the hydrogen bond became widely known as the universal interaction, thus playing a key role in many molecular processes.

Through the available theoretical approaches, many of these processes can be unveiled on the basis of the molecular parameters of the subject intermolecular system, such as the variation of bond length and mainly the frequency shift observed in the proton donor.

New York, ; Hadzi, D. Novapigacao Nova36 B1 However, the weakness of the interaction strength is caused by dispersion forces, whose contribution decisively lead to the stabilization of complexes formed via van der Waals interactions.

Among these, electrostatic partition governs the formation of the hydrogen bonds, whose energies are arguably high.

It is through the application of an electronic partition approach called Symmetry-Adapted Perturbation Theory SAPT that the nature of hydrogen bonds and van der Waals interactions can be unveiled according to the contribution of electrostatic, charge transfer, exchange repulsion, polarization, and dispersion terms.

Moreover, to identify the preferential interaction sites for proton donors and acceptors, the molecular electrostatic potential MEP is useful in this regard. W; Atoms in Molecules. B,
