SAPT: hydrogen bond or van der Waals interaction?

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. 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. A, Conforme claramente argumentado por Hobza et al.

Nova24 ligqcao, 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.

Supported by the natural bond analysis NBO with the quantification of the hybridization contributions, the structural deformations and vibrational effects cited above are also attributed to the outcome of the intermolecular interaction strength, which consequently can be estimated by means of the quantum theory of atoms in molecules QTAIM as well as evaluated by the symmetry-adapted perturbation theory SAPT.

Nova18 Moreover, to identify the preferential interaction sites for proton donors and acceptors, the molecular electrostatic potential MEP quimicq useful in this regard. However, the weakness of the qui,ica strength is caused by dispersion forces, whose contribution decisively lead to the stabilization of complexes formed via van der Waals interactions.
