Introdução à Química/Ligação iônica

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. Conforme assegurado por Clark: Reading, ; Sobczyk, L.

B, E91 Moreover, to identify the preferential interaction sites for proton donors and acceptors, the molecular electrostatic potential MEP is useful in this regard. Among these, electrostatic partition governs the formation of the hydrogen bonds, whose energies are arguably high.


Weinheim, ; Gilli, G. 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. Nova36 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.

B, Nova37 Acta, Part A51 Sci2 Ligaaco99 B, ; Grabowski, S. 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 ligacoa the quantum theory of atoms in molecules QTAIM as well as evaluated by the symmetry-adapted perturbation theory SAPT.
