As I’m sure the readers of this blog know, NMR spectroscopy is used widely across all branches of chemistry due to its powerful structure elucidation capabilities and the inherently quantitative nature of the technique. Organic relies primarily on 1H/13C experiments where as inorganic chemistry can expand to other nuclei, like 31P and 11B. However, there are many other applications for NMR other than just structural elucidation. Perhaps a lesser known application of NMR spectroscopy, is its ability to determine the isotopic ratio of elements! In this blog post I would like to demonstrate a novel method to determine the 10B/11B isotopic ratio using our NMReady-60e and 1H NMR spectra!

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?

What is process analytical technology (PAT) and why is it so important?PAT is an extremely powerful and useful tool for analyzing, optimizing and controlling chemical processes. Chemical, food and pharmaceutical industries could especially benefit from this technique. In earlier days, chemical processes were primarily monitored by physical techniques, such as temperature, pH, pressure etc..

Hello fellow NMR enthusiasts, have you ever wondered what tritium (3H) looks like via NMR? I know I have, and today, I would like to share some data with you. Read noww.

Given the superior resolution of our 100 MHz instrument, we can perform structure elucidation on increasingly large molecules. As molecules get more complex, as do the suite of experiments that can be used to…

It is common to mention the frequency of an NMR instrument instead of its field. When someone says: I have in my laboratory a 100 MHz instrument, it means that a spectrometer where the protons precess with a frequency of 100 MHz (Lamour frequency) is available in the lab…

NMR users can deal with spectrum evaluation in the daily work, but how is the spectrum information stored in the time domain (FID)? Read more.

Brucine is a structurally complex molecule, commonly found in the bark and seeds of the Strychnos nux-vomica tree, which is native to India and southeast Asia.1 A toxic alkaloid, brucine is typically present alongside strychnine, a structurally almost identical molecule that is more toxic than brucine.

Magnets used to manufacture low-field and high-field NMR spectrometers are not perfect and the magnetic field that they generate is prone to drift for a variety of reasons. However, during an NMR experiment it is important to keep the magnetic field as stable as possible to prevent the signals from drifting. This is taken care of by the lock system.

‘The spectra were analyzed according to first order’. Does this sound familiar to you? Most of the supporting information documents out there contain this sentence. You find yourself asking ‘why does nobody care about second order effects?’, then check out this high-order blog entry on the topic.
