A C5FH probe, a powerful tool for analyzing fluorine-containing compounds, is revised and equipped with a field gradient coil, to be a C5FH/FG2 probe. By utilizing field gradient pulses, two-dimensional 13C- 1H correlation measurements with 19F decoupling, for example, can be performed in a short time.

With 19F decoupling
For fluorine-containing compounds, 19F decoupling removes splittings due to couplings with 19F nuclei and simplify the spectra, as shown in Fig.2. Thus, a C5FH/FG2 probe permits easy and short-time measurements in multi-dimensional NMR spectroscopy.
