19F Benchtop NMR Spectroscopy for Rapid Hydroxyl Value Determination in Polymers
When analyzing polymers using nuclear magnetic resonance (NMR) spectroscopy, well-defined end-groups (e.g., methoxy, acrylate, vinyl) are typically desired, as these allow for a direct comparison between these end-groups and the repeating monomeric units. This provides a path for rapid and facile determination of the number of repeating units in a polymer, as well as its number-average molecular weight (Mn). Read more.

Unsymmetric Carbon Satellites in Fluorine-19 NMR
In the 19F NMR spectrum of DCBTF, we can observe the singlet resonance of the trifluoromethyl fragment at δ = −63.07 ppm. While it might not jump into your eye at first glance, please note that the carbon satellites are not centered at the "main signal", which is what we are used to from 1H NMR spectra. Read more
