probes_atom fluorine-19 atom 19F nuclear magnetic resonance spectroscopy CHMO:0000597 19F nuclear magnetic resonance spectrometry Spectroscopy where the energy states of 19F nuclei placed in a static magnetic field are interrogated by inducing transitions between the states via radio frequency irradiation. Each experiment consists of a sequence of radio frequency pulses with delay periods in between them.
