Selective Fluorine NMR Spectroscopy

19 F is a very sensitive NMR active nucleus that provides a wealth of structural detail.  The chemical shift information and coupling data (between fluorine nuclei and other atoms) found in 19 F NMR spectra allows the assignment of both the nature and location of fluorine atoms within molecules.

Example spectra.

Technical information:

19 F NMR spectra are acquired using a high-resolution selective 19 F probe that allows 1D and 2D 19 F NMR, and direct observation of 19 F with 1 H decoupling (also 1 H observe with 19 F decoupling).

In addition, the probe includes a 2 H lock channel and variable temperature capability. Pulsed field gradient coils (PFG) are utilised to suppress artefacts and accelerate acquisition times for useful multi-dimensional experiments.
