Nuclear magnetic resonance spectroscopy (NMR) has always constituted a central analytical technique in chemistry. Previously, experiments were performed and interpreted by NMR experts. Keeping the instruments running was a central task of dedicated technicians. Teaching how to interpret NMR spectra based on chemical shifts and scalar couplings was a central task in the curriculum. The investigated structures usually fell into the small-molecules category. This has all dramatically changed in the meantime.
