The Spectrum Characteristic of Hydrogen Bonds [PDF]

open access: green, 1937
It has been observed that in certain substances containing hydroxyl hydrogen the relatively narrow and intense absorption bands which ordinarily are characteristic of the O-H group appear to be absent.

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

open access: yesCommunications 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]

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

Circular hydrogen bonds [PDF]

open access: bronzeNature, 1981
CIRCULAR hydrogen bonds present a new, experimentally demonstrated principle showing how hydration water molecules and hydroxyl groups of macromolecules can cooperate to form a network-like pattern. Quantum chemical calculations show that chain-like H-bonds in the crystal lattice1 are energetically favoured above individual ones2,3.

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 ...

Quantum Nature of the Proton in Water-Hydroxyl Overlayers on Metal Surfaces [PDF]

open access: yes, 2010
Using ab initio path-integral molecular dynamics, we show that water-hydroxyl overlayers on transition metal surfaces exhibit surprisingly pronounced quantum nuclear effects.

Hydrogen and Lithium Bonds—Lewis Acid Units Possessing Multi-Center Covalent Bonds

open access: yesMolecules, 2021
MP2/aug-cc-pVTZ calculations were carried out on complexes wherein the proton or the lithium cation is located between π-electron systems, or between π-electron and σ-electron units.
