Hydrogen bonding is a form of weak attractive force between molecules that contain an electric charge. It is caused by electrostatic attraction and can alter the chemical properties of the molecules, including raising the melting point. The force is stronger than a simple dipole-to-dipole force bu...
The quantum behaviour of bonding hydrogen also influences dynamical processes such as vibrational spectroscopy and hydrogen or proton transport.doi:10.1080/00268976.2012.728636P. P. SchmidttaylorMolecular Physics
The effects of aromatic fluorine substitutions on aromatic rings are also investigated, and it is found that these substitutions can have large effects on the hydrogen bonding interactions that occur in our model systems, making them substantially stronger. This finding offers a new mechanism for the...

There is thus no hydrogen bonding between pyrrolidinone molecules and tribromide ions. The colinear arrangement of tribromide ions and the channel structure for the compound are, to our knowledge, unique amongst published tribromide structures. Similar situations are rare even with the more numerous ...
We have examined intramolecular hydrogen bonding in four homologous compounds, N‐acetyl‐, N‐propionyl‐, N‐i‐butyryl‐, and N‐pivaloyl‐proline‐methylamide, in methylene chloride, by means of1H‐nmr and ir measurements. At room temperature, the majortransconformer of MeCO‐Pro‐NHMe appea...
In Section 4.1 “Covalent Bonds”, we stated that the covalent bond in the hydrogen molecule (H2) has a certain length (about 7.4 × 10−11 m). Other covalent bonds also have known bond lengths, which are dependent on both the identities of the atoms in the bond and whether the bo...
By controlling the temperature–time-hydrogen pressure, an optimal hydrogenation formula was obtained.Low temperature diffusion bonding was achieved at the superplastic forming temperature.Microstructure and phase of Ti-4.5Al-3V-2Mo-2Fe alloy exhibit obvious variations with different levels of hydrogen cont...

Charge-assisted hydrogen bonds (CAHBs) of N–H···Cl, N–H···Br, and P–H···Cl type were investigated using advanced computational approach (MP2/aug-cc-pVTZ level of theory). The properties of electron density function defined in the framework of Quantum Theory of Atoms in Molecu...
