A topologia molecular QTAIM e a descrição mecânico-quântica de ligações de hidrogênio e ligações de di-hidrogênio

Abstract: Recebido em 26/6/09; aceito em 10/1/10; publicado na web em 23/4/10 THE QTAIM MOLECULAR TOPOLOGY AND THE QUANTUM-MECHANICAL DESCRIPTION OF HYDROGEN BONDS AND DIHYDROGEN BONDS. Hydrogen bonds formed through the interaction between a high electronic density center (lone electron pairs, π or pseudo-π bonds) and proton donors cause important electronic and vibrational phenomena in many systems. However, it was demonstrated that proton donors interact with hydrides, such as alkali and alkaline earth metals (BeH 2 ,… Show more

“…The QTAIM methodology is a quantum model considered innovative in studies of chemical bonds but also is effective in characterizing intramolecular and/or intermolecular interactions [47]. Thus, QTAIM calculations are very important to check the influence of hydrogen bonds in the iso values [40][41][42][43][44][45][46][47][48][49][50][51][52]; this model was developed by Bader [48].…”

“…5) of BCPs (w, y, and z) and Bond Paths (BP) along the chemical bonds [98] (through the BCP pointed by w) and interatomic interactions (through the BCP pointed by z), in which it can be formed by low, median or high charge density concentrations [99][100][101][102][103]. Such designations can be predicted through the obtained Table 6 Values of the QTAIM properties of the p bonds in the I-IV systems.…”

“…Designed by Bader, the QTAIM has been applied successfully in several types of investigation [105,106], including characterization of hydrogen bonds, where QTAIM is one of the procedures used routinely [107][108][109][110][111]. Very recently, a research group stated that the QTAIM topological condition for recognizing hydrogen bond formation is a BCP with coordinates (3,−1) [112].…”
