Hydrogen Bonding

Science, 1992
The article "Benzene forms hydrogen bonds with water" by S. Suzuki, et al. (14 August., p. 942) represents a major advance in our understanding of their interactions between water and aromatic structures. The authors show that benzene forms hydrogen bonds with water through the π electron system of benzene.

Hydrogen bonds, improper hydrogen bonds and dihydrogen bonds

Journal of Molecular Structure: THEOCHEM, 2003
Abstract The structures, interaction energies and vibrational spectra of a large number of molecular complexes, formed by binary combination of the covalent hydrides of some of the elements of the first two rows of the periodic table, have been determined by means of ab initio molecular orbital theory at the MP2 level, using the 6-311++G(d,p) basis ...

Hydrogen Bonded Arrays: The Power of Multiple Hydrogen Bonds

Journal of the American Chemical Society, 2012
Hydrogen bond interactions in small covalent model compounds (i.e., deprotonated polyhydroxy alcohols) were measured by negative ion photoelectron spectroscopy. The experimentally determined vertical and adiabatic electron detachment energies for (HOCH(2)CH(2))(2)CHO(-)(2a), (HOCH(2)CH(2))(3)CO(-) (3a), and (HOCH(2)CH(2)CH(OH)CH(2))(3)CO(-) (4a)reveal ...

The hydrogen bond

Chemical Physics Letters, 2008
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 ...

Bonding to Hydrogen

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 ...

Hydrogen-bond filtration

Nature Reviews Chemistry, 2020
Self-organization of water molecules around solute ions can affect how they permeate through nanoporous liquid-crystalline membranes.

Hydrogen bonding with polonium

Physical Chemistry Chemical Physics, 2022
Beyond atomic electronegativity: polonium can form hydrogen bonds even if its electronegativity is less than that of hydrogen. The X–H⋯Po H-bonds are dominated by dispersion and can have H-bond energy comparable to that of conventional H-bonds.
