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 ...

Charge transfer across C–H⋅⋅⋅O hydrogen bonds stabilizes oil droplets in water

Science, 2021
Description Why oil and water do not mix It is well known that oil forms stable droplets that carry a negative electrophoretic mobility (and negative charge) upon dispersing in water. However, the underlying mechanism is a long-debated topic.

Hydrogen Bonds: Raman Spectroscopic Study

International Journal of Molecular Sciences, 2021
The work outlines general ideas on how the frequency and the intensity of proton vibrations of X–H···Y hydrogen bonding are formed as the bond evolves from weak to maximally strong bonding.

Direct Photocatalyzed Hydrogen Atom Transfer (HAT) for Aliphatic C–H Bonds Elaboration

Chemical Reviews, 2021
Direct photocatalyzed hydrogen atom transfer (d-HAT) can be considered a method of choice for the elaboration of aliphatic C–H bonds. In this manifold, a photocatalyst (PCHAT) exploits the energy of a photon to trigger the homolytic cleavage of such ...
