Zeeman first observed the strange behavior of certain nuclei when subjected to a strong magnetic field at the end of the nineteenth century, but the practical use of the so-called “Zeeman effect”was only made in the 1950s when NMR spectrometers became commercially available. Most of the methods use gas chromatography or infrared spectroscopy. Figure from J. Keeler, Understanding NMR Spectroscopy, 2nd, Wiley, West Sussex (2010). Carbon C13 NMR Spectroscopy.
