2D NMR Experiments - HETCOR
2D NMR experiments can provide an abundance of information for the structural elucidation of chemical compounds. An older example of a 2D experiment is the heteronuclear correlation (HETCOR) sequence. In this experiment, two different nuclei (usually 13C and1H) are correlated through single bond spin-spin coupling, revealing which proton and carbon groups are bonded to each other.

Two solvents, two different spectra - Aromatic Solvent Induced Shifts
In my opinion, one of the most helpful papers[1] in the field of NMR spectroscopy in Organic Chemistry consists of ‘just’ two tables. In these, the chemical shifts (1H and 13C) of as many as forty-two common impurities in twelve different deuterated solvents are listed. This is gold! Why?
Introducing......the newest addition to our family!
We are pleased to introduce the most powerful benchtop NMR available……the Nanalysis 100 MHz benchtop NMR!!
Heteronuclear Spin-Spin Coupling on the Nanalysis 60PRO
Spin-spin coupling is an important facet of 1H NMR spectroscopy, as crucial details about the structure of a molecule are revealed based on the pattern of multiplets observed. Read more.
Getting COSY with the TOCSY Experiment
2D NMR experiments can provide a wealth of information to aid in the structural elucidation of chemical compounds. Of the many 2D NMR experiments available, the homonuclear correlation spectroscopy (COSY) sequence is one of the most popular and is used to identify which spin systems are directly coupled to each other. As an example, the 1H-1H COSY spectrum of 1-propanol recorded on the NMReady-60 is shown below in Figure 1.
Beyond structural elucidation, introduction to qNMR – Part I
…more and more analytical and industrial laboratories have started employing quantitative nuclear magnetic resonance (qNMR) spectroscopy as a tool for content assignment (due to its superb structural elucidation abilities) and quantification of purity in a sample. Read More.
What's the 'ism' of today? Keto-Enol Tautomerism
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 more here.
