What can we learn from NMR about Hydrogen Bonds ?Grzesiek, Stephan
Hydrogen Bond:Hydrogen bonding is that the interaction involving a atom placed between a combine of alternative atoms having a high affinity for electrons; such a bond is weaker than an bond or bond however stronger than van der Waals forces. element bonds will exist between atoms in n...
Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
etc., was first conceived and realized in the early decades of the last century, when it was not clear why the melting points and latent heats of water, ammonia, or hydrogen fluoride were higher than those of other hydrides of heavier elements (such as H2S, HCl, PH3, SiH4, etc.). St...
Advanced theory of the hydrogen bond The hydrogen bond remains a fairly mysterious object in the theoretical study of quantum chemistry and physics. Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is slig...
Equation of motion coupled-cluster calculations (EOM-CCSD) have been performed to obtain 15N−15N and 17O−17O coupling constants (2hJX-X) across N−H+−N and O−H+−O hydrogen bonds in a series of protonated dimers. 2hJX-X values are dominated by the Fermi-contact term and...
DNA:Hydrogen bonds form between base pairs. This gives DNA itsdouble helix shapeand makes replication of the strands possible, as they "unzip" along the hydrogen bonds. nylon:Hydrogen bonds are found between the repeating units of the polymer. ...
In non-buffered aqueous solutions, ATP is unstable and hydrolyzes into ADP and phosphate. This is because the P-O-P bond in ATP is weaker than the formed phosphate bonds, and the reaction releases energy through hydrogen bonding between the products and water, resulting in an exothermic and ...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportio
