"Hydridic Hydrogen-Bond Donors" Are Not Hydrogen-Bond Donors. [PDF]

J Am Chem Soc
Herein, we dismiss a recent proposal by Civiš, Hobza, and co-workers to modify the IUPAC definition of hydrogen bonds in order to expand the scope from protonic Y-Hδ+ to hydridic Y-Hδ- hydrogen-bond donor fragments [J. Am. Chem. Soc. 2023, 145, 8550].

Quantifying the ability of the CF2H group as a hydrogen bond donor [PDF]

Beilstein Journal of Organic Chemistry
The CF2H group can act as a hydrogen bond donor, serving as a potential surrogate for OH or SH groups but with a weaker hydrogen bond donation ability.

The Relation Between the Energy of a Hydrogen Bond and the Frequencies of the O[Single Bond]H Bands [PDF]

, 1940
It has previously been pointed out (1) that there appears to be a relation between the energy of a hydrogen bond and the shift of the frequency of the O-H bands which accompanies the formation of the bond.

Nature of the Hydrogen Bond Enhanced Halogen Bond [PDF]

Molecules, 2021
The factors responsible for the enhancement of the halogen bond by an adjacent hydrogen bond have been quantitatively explored by means of state-of-the-art computational methods. It is found that the strength of a halogen bond is enhanced by ca.

The Hydrogen Bond of QCD [PDF]

Physical Review D, 2019
Using the Born-Oppenheimer approximation, we show that exotic resonances, X and Z, may emerge as QCD molecular objects made of colored two-quark lumps, states with heavy-light diquarks spatially separated from antidiquarks.

Revealing the Reasons for Degeneration of Resonance-Assisted Hydrogen Bond on the Aromatic Platform: Calculations of Ortho-, Meta-, Para-Disubstituted Benzenes, and (Z)-(E)-Olefins

Molecules, 2023
The energies of the O−H∙∙∙O=C intramolecular hydrogen bonds were compared quantitatively for the series of ortho-disubstituted benzenes and Z-isomers of olefins via a molecular tailoring approach.

Systematic Hydrogen‐Bond Manipulations To Establish Polysaccharide Structure–Property Correlations [PDF]

, 2019
A dense hydrogen‐bond network is responsible for the mechanical and structural properties of polysaccharides. Random derivatization alters the properties of the bulk material by disrupting the hydrogen bonds, but obstructs detailed structure–function ...

Studies of Hydrogen Bond Vibrations of Hydrogen-Disordered Ice Ic

Crystals, 2021
The hydrogen-disordered structure of ice, Ic, makes it difficult to analyze the vibrational normal modes in the far-infrared region (i.e., the molecular translation band).
