On the similar spectral manifestations of protonic and hydridic hydrogen bonds despite their different origin [PDF]

Communications Chemistry
Previously studied complexes with protonic and hydridic hydrogen bonds exhibit significant similarities. The present study provides a detailed investigation of the structure, stabilization, electronic properties, and spectral characteristics of protonic ...

Dynamic anti-correlations of water hydrogen bonds [PDF]

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

PLoS 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

Química 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.

Hydrogen-Bonds Structure in Poly(2-Hydroxyethyl Methacrylate) Studied by Temperature-Dependent Infrared Spectroscopy

Frontiers in Chemistry, 2014
Hydrogen-bonds structure in poly(2-hydroxyethyl methacrylate) (PHEMA) were investigated by means of temperature-dependent infrared (IR) spectroscopy. Spectral variations involved with the OH•••OH and C=O•••HO types of hydrogen-bonds were found around the
