Eat Your Heart Out Mass Spec: Measuring 10B/11B Isotopic Ratio by NMR Spectroscopy

Eat Your Heart Out Mass Spec: Measuring 10B/11B Isotopic Ratio by NMR Spectroscopy

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!

To apodize or not to apodize - the age old question

To apodize or not to apodize - the age old question

Are you familiar with the Apodization tool in Mnova? Apodization (also referred to as Weighting or Windowing) literally translates to ‘cutting off the feet’ from the original Greek. In this case, the ‘feet’ are the leakage or wiggles that appears when the NMR signal rapidly decays to zero. As such, apodization can enhance the resolution or the sensitivity (S/N ratio) in the spectrum and even remove truncation artefacts after data has been collected. This function is particularly useful for spectra acquired on a benchtop NMR instrument due to the lower S/N ratio compared to spectra collected on high-field instruments.
