The Journal of Physical Chemistry A, 2006
In this Article we extend the idea of detecting a hydrogen bond solely on one single quantum chemically determined descriptor. We present an improvement of the method introduced by Reiher et al. (Theor. Chim. Acta 2001, 106, 379), who mapped the strength of the hydrogen bond onto an easily accessible quantity, namely, the two-center shared-electron ...

Persistent Hydrogen‐Bonded and Non‐Hydrogen‐Bonded Phenoxyl Radicals
Chemistry – A European Journal, 2011AbstractThe production of stable phenoxyl radicals is undoubtedly a synthetic chemical challenge. Yet it is a useful way to gain information on the properties of the biological tyrosyl radicals. Recently, several persistent phenoxyl radicals have been reported, but only limited synthetic variations could be achieved.

Abstract The concept of the hydrogen bond is a century old but remains youthful because of its vital role in so many branches of science and because of continued advances in experiment, theory and simulation. We discuss the structural and energetic characteristics of normal hydrogen bonds X–H···Y as well as some exceptions to the normal, including ...

Stickiness of the Hydrogen Bond
Annalen der Physik, 2018AbstractThe dielectric response of bulk water follows laws of continuum electrostatics, a scheme often extrapolated without justification to treat confined interfacial water, where the Debye polarization ansatz breaks down and discrete effects matter.

Crystallography Reviews, 1995
This article focusses on the crystallographic research aimed at a better understanding of hydrogen bonds which has been published since January 1990. In the interest of continuity, earlier work is quoted when it relates to that published during this period.

American Scientist, 2012
My first encounter with H2 was typical for a boy in the age of chemistry sets that had some zing to them. My set, made by A. C. Gilbert Co., contained some powdered zinc. It had no acids, but it taught you to generate them from chemicals it included (for instance HCl from NaHSO4 and NH4Cl), or—the manual said— you could buy a small quantity from your ...

Reports on Progress in Physics, 1952
A survey is given of the infra-red spectra of substances possessing hydroxyl groups and of the position of the O-H valence vibration in the solid, liquid and gaseous state and in dilute solutions. The spectra of water, alcohols and carboxylic acids are discussed separately; and evidence for molecular association is adduced from the experiments on ...
