Developed in the 1940s and 1950s, nuclear magnetic resonance (NMR) spectroscopy measures physical and chemical properties of atoms or molecules by measuring change in the magnetic resonance of the nuclei of atoms. The process is used by scientists for a variety of applications, such as substance identification. In biomolecular science, NMR supports discovery and identification of new drugs, disease and metabolic research, study of structural biology, and more.
