Infrared Absorption Associated with Strong Hydrogen Bonds [PDF]
, 1958 Several investigators have proposed that there exists a more or less unique relation between the O-O distance in O-H-O hydrogen bonds and the shift of O-H vibrational frequency. [1-5] However, the meager intensities of some bands which have been ascribed

Crystal structure of tris(piperidinium) hydrogen sulfate sulfate
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title molecular salt, 3C5H12N+·HSO4−·SO42−, each cation adopts a chair conformation. In the crystal, the hydrogen sulfate ion is connected to the sulfate ion by a strong O—H...O hydrogen bond. The packing also features a number of N—H...O hydrogen

Universal features in lifetime distribution of clusters in hydrogen bonding liquids [PDF]
, 2021 Hydrogen bonding liquids, typically water and alcohols, are known to form labile structures (network, chains, etc...), hence the lifetime of such structures is an important microscopic parameter, which can be calculated in computer simulations. Since these cluster entities are mostly statistical in nature, one would expect that, in the short time ...

Chemistry - An Asian Journal, 2019 Hydrogen bonds are a complex interplay between different energy components, and their nature is still subject of an ongoing debate. In this minireview, we therefore provide an overview of the different perspectives on hydrogen bonding.

Do Hydrogen Bonds Influence Excitonic Splittings?
CHIMIA, 2016 The excitonic splitting and vibronic quenching of the inversion-symmetric homodimers of benzonitrile, (BN)2, and meta-cyanophenol, (mCP)2, are investigated by two-color resonant two-photon ionization spectroscopy.

Hydrogen bond analysis of confined water in mesoporous silica using the reactive force field [PDF]
Mol. Sim. 45, 1437-1446 (2019), 2019 The structural and dynamical properties of water confined in nanoporous silica with a pore diameter of 2.7 nm were investigated by performing large-scale molecular dynamics simulations using the reactive force field. The radial distribution function and diffusion coefficient of water were calculated, and the values at the center of the pore agreed well

1-(2,6-Dichlorobenzoyl)-3-(3-methoxyphenyl)thiourea [PDF]
, 2008 The two aromatic rings in the title compound, C15H12Cl2N2O2S, enclose a dihedral angle of 37.49 (6)°. The molecule exists in the solid state in its thione form with typical thiourea C-S and C-O bonds lengths, as well as shortened C-N bonds.

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. 3 kcal/mol when the halogen donor simultaneously operates as a halogen bond donor and a hydrogen bond ...

Side chain to main chain hydrogen bonds stabilize a polyglutamine helix in a transcription factor
Nature Communications, 2019 Polyglutamine (polyQ) tracts are regions of low sequence complexity frequently found in transcription factors. Tract length often correlates with transcriptional activity and expansion beyond specific thresholds in certain human proteins is the cause of ...
