Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field ) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process … See more Nuclear magnetic resonance was first described and measured in molecular beams by Isidor Rabi in 1938, by extending the Stern–Gerlach experiment, and in 1944, Rabi was awarded the Nobel Prize in Physics for … See more NMR spectroscopy is one of the principal techniques used to obtain physical, chemical, electronic and structural information about molecules due to the chemical shift of the … See more • Benchtop NMR spectrometer • Larmor equation (Not to be confused with Larmor formula).
