NMR is an abbreviation for Nuclear Magnetic Resonance. The advantages of NMR for the analysis of molecular structures at the atomic level are that sample measurements are non-destructive and that there is little sample preparation required. NMR spectroscopy is a versatile tool that provides information not only on the structures, but also on the dynamics of various biological and synthetic molecules at an atomic level. The investigated samples are put in a magnetic field that is tens of thousands of times stronger than the earth’s magnetic field. The NMR method is very sensitive to the features of molecular structure because the neighboring atoms influence the signals from individual nuclei as well and this is important for determining the 3D-structure of molecules. With NMR spectroscopy one can study liquid, solid and semi-liquid samples. Fields of application include bio, foods, chemistry, as well as new ones such as batteries.
