NMR is a great tool for the analysis of molecular properties such as the amide bond, which has a restricted rotation around the C–N bond. In Biochemistry, the amide bond is referred to as the peptide bond. This bond is formed by the union of a carboxyl group of one amino acid with the amino group of another amino acid. Read more.

Tautomers are constitutional isomers that interconvert into each other by an exchange reaction, most commonly a proton transfer. Such two isomers can for example be a ketone and an enol. Keto-enol tautomerism (KET) becomes possible when there are hydrogen atoms adjacent to a carbonyl group (these hydrogen atoms are called α hydrogens). This tautomerism is depicted in Scheme 1 and is also discussed…

In this blog post, we show an example for on-line flow reaction monitoring via 19F NMR spectroscopy using the compact benchtop NMR. 1-855-NMREADY (667-3239) toll-free in the US and Canada

Electronegativity is a concept that we have to study and understand early in our science or engineering degrees. In chemistry this concept stays with us and we commonly invoke it in order to explain multiple phenomena what we observe or study…and of course, NMR is not the exception!

2,4-pentanedione (aka acetylacetone, acetylacetonato or acacH) is not only a ubiquitous ligand (AND ligand precursor!) for beautifully coloured organometallic complexes[1-3].. Read more.
