nuclear magnetic resonance (NMR)

Selective absorption of very high-frequency radio waves by certain atomic nuclei subjected to a strong stationary magnetic field. Nuclei that have at least one unpaired proton or neutron act like tiny magnets. When a strong magnetic field acts on such nuclei, it sets them into precession. When the natural frequency of the precessing nuclear magnets corresponds to the frequency of a weak external radio wave striking the material, energy is absorbed by the nuclei at a frequency called the resonant frequency. NMR is used to study the molecular structure of various solids and liquids. Magnetic resonance imaging, or MRI, is a version of NMR used in medicine to view soft tissues of the human body in a hazard-free, noninvasive way.

9780470723012 Modelling 1H NMR spectra of organic compounds; theory, applications and NMR prediction software.
In 2006, EXPEC ARC teamed up with Baker Hughes and the Reservoir Description and Simulation Department to develop the next-generation NMR technology useful for obtaining real-time measurements in angled and horizontal wells of small diametres.
While one may be impressed by the sheer size of NMR systems with high-strength magnets, the probe, which provides the means to interface the sample with the instrument, is an important--if small in size--contributor to the performance of an NMR system.
