Origin of Chemical Shifts
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…
Relation between the FID and the NMR spectrum
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.
Analysis of Brucine at 100 MHz – Getting COSY with Correlations
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.
How does the lock work?
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.
To Decouple or Not to Decouple, that is the question. Also…Acids
Acidity is something that you encounter on a daily basis, probably without even realizing it. The tangy taste of an orange (citric acid), that Vitamin C tablet you took this morning (ascorbic acid), those terrible jeans from the 80’s that you still wear (acid wash). My favourite acid is acetic acid.
Just Keep Swimming: NMR For Omega-3 Supplements
Many people don't get enough omega-3s in their diet because their main source for them is fish. Fortunately, the composition of fish oil supplements can be analyzed using NMR benchtop spectrometers so people can get the omega-3s and PUFAs they need for a well-balanced diet.
Your Nanalysis 60 Order!
‘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.
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…
Deuterated Solvents
If you’ve ever prepared an NMR sample, you’re familiar with the fact that we almost always use deuterated solvents to dissolve our samples of interest…
Why 100 MHz Benchtop NMR?
While low-field NMR has extremely favourable accessibility and affordable characteristics, the most common question that we get asked about our family of benchtop NMR spectrometers is with respect to any trade-offs that come from moving to lower-field.
