A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...

The existence of intermolecular hydrogen bonds between carbazole and DMF was clarified at the molecular level by various advanced NMR technologies, which promoted the separation of carbazole and ...

Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond.

Water has a complex hydrogen bonding network that should be disrupted by the presence of ions. However, studies have shown that there is little disruption to the hydrogen-bonding network.

However, most of the detailed studies of this problem have been concerned with intermolecular hydrogen bonds, and it is suggested here that in the cyclic systems involved in intramolecular ...

We investigated rearrangements of the hydrogen-bond network in water by measuring fluctuations in the OH-stretching frequency of HOD in liquid D 2 O with femtosecond infrared spectroscopy. Using ...

Hydrogen bonds form between two atoms and a hydrogen atom. Atoms, such as oxygen, can be covalently bound to hydrogen, and giving the hydrogen (H) in the OH group a slight positive charge due to ...

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. This technique can be used ...

Elements are held together in different ways and the properties of chemical compounds are determined by the bonding between atoms and the attractive intermolecular forces between molecules.

The copolymer increased the proportion of intermolecular hydrogen bond between copolymer and water molecule, but decreased the proportion of intramolecular hydrogen bond between water molecule.

We investigated rearrangements of the hydrogen-bond network in water by measuring fluctuations in the OH-stretching frequency of HOD in liquid D2O with femtosecond infrared spectroscopy. Using ...
