Dynamic anti-correlations of water hydrogen bonds [PDF]

open access: yesNature Communications
Water is characterized by strong intermolecular hydrogen bonds (H-bonds) between molecules. The two hydrogen atoms in one water molecule can form H-bonds of dissimilar length. Although intimately connected to water’s anomalous properties, the details and

The interplay between hydrogen bonds and stacking/T-type interactions in molecular cocrystals [PDF]

open access: yesCommunications Chemistry
Supramolecular synthon and hydrogen bond pairing approaches have influenced the understanding of cocrystal formation for decades, but are hydrogen bonds really the dominant interaction in cocrystals?

The Role of Backbone Hydrogen Bonds in the Transition State for Protein Folding of a PDZ Domain. [PDF]

open access: yesPLoS ONE, 2014
Backbone hydrogen bonds are important for the structure and stability of proteins. However, since conventional site-directed mutagenesis cannot be applied to perturb the backbone, the contribution of these hydrogen bonds in protein folding and stability ...

A topologia molecular QTAIM e a descrição mecânico-quântica de ligações de hidrogênio e ligações de di-hidrogênio The QTAIM molecular topology and the quantum-mechanical description of hydrogen bonds and dihydrogen bonds

open access: yesQuímica Nova, 2010
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.
