Bond-length bond-strength correlation for hydrogen-bonded carboxyl groupsAn empirical correlation is established between the C = O and C–OH lengths of hydrogen-bonded carboxylic acids, indicating a decrease of π-bond order of C = O and an increase for C–OH with decreasing O…O distanc...
The hydrogen is found to bind to the Os in a sideways fashion. The potential energy surface with respect to the H-H stretch is predicted to be extremely shallow; thus, electron correlation accounted for at the MP2 level of theory has a large effect on bot-h the H-H bond length and ...

Hydrogen bondsare intermediate in terms of strength and length when compared tovan der waal's forcesandcovalent bonds. A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewisbaseand acceptor atom likecarboxylic acid. The larger the number...
The new atom, that is in the hydrogen bond, just remains in an electrostatic attraction with that hydrogen atom. Hydrogen bonds are easier to break than covalent or ionic bonds because they do not involve the sharing or transfer of electrons which creates a stronger bond....

In the present work, we introduce two new metrics i.e. hydrogen-bond strength and charge-transfer between the donor/acceptor water molecules as a measure of hydrogen-bond rearrangement dynamics. Further, we also employ a simple model based on energy flux
For N–H N hydrogen bonds, the dependence of the N–H length on the H N distance is studied using neutron diffraction data; this dependence is the same for both charged and uncharged N–H donors; geometry predictions for strong hydrogen bonds and values for the shortest possible N N and...
The author has shown previously that the Golden ratio based ionic radiiexplain quantitatively the bond lengths in completely ionic as well as partially ionicbonds including hydrogen bonds. These ionic radii and covalent radii were shown to be additive in small as well as large molecules. This work...
