Nuclear magnetic resonance NMR ) is a physical phenomenon described independently by F. Bloch and E. M. Purcell in 1946 both of whom shared the Nobel Prize in physics in 1952 for their discovery. It involves the interaction of atomic nuclei placed in an external magnetic field with an applied electromagnetic field oscillating at a particular frequency . Magnetic conditions within the material are measured by monitoring the radiation absorbed and emitted by the atomic nuclei. NMR is used as a spectroscopy technique to obtain physical, chemical, and electronic properties of molecules . It is also the underlying principle of Magnetic Resonance Imaging . NMR is one of the techniques used to build quantum computers How NMR works In NMR, the sample to be tested is placed in a static external

Feedback Nuclear Magnetic Resonance (NMR) Analysis The mission of the Almaden Research Center NMR Facility is to develop new measurement techniques and to provide a limited routine service for applications of NMR spectroscopy in the area of information technology related materials problems. At ARC, NMR spectroscopy is used for structure determination/characterization relating to the following materials problems: Photolithographic Systems This class of materials includes the polymers, photo-acid generators, small-molecule additives, and casting solvents that make up a photoresist. Quantitative solution-state 13C NMR allows for total component analysis of both bulk resist solutions and processed thin films. Polymeric Dielectric Materials Solid-state NMR techniques such as combined Cross-Polarization and Magic-Angle Spinning (CPMAS) are particularly important for the characterization of these materials due to their insolubility in final cured form. NMR spectroscopy is one of the few techniques that can give information on the microscopic chemical structure of these materials as a function of processing conditions. Head/Disk Interface Materials Amorphous carbon overcoats and perfluoropolyether lubricants are included in this class of materials. Solid-state 13C NMR has been used to learn about structural variations in amorphous CHx films as a function of sputter conditions. The composition, molecular weight, and decomposition products of perfluoropolyethers can be determined using solution-state 19F NMR techniques.

55. Nuclear Magnetic Resonance Spectroscopy -- From Eric Weisstein's World Of Physic nuclear magnetic resonance Spectroscopy, By applying a magnetic field,nuclear energy levels are split. By observing nuclear transitions http://scienceworld.wolfram.com/physics/NuclearMagneticResonanceSpectroscopy.htm

Modern Physics Particle Physics Magnetic Resonance Modern Physics ... General Spectroscopy Nuclear Magnetic Resonance Spectroscopy By applying a magnetic field, nuclear energy levels are split. By observing nuclear transitions in the microwave and radio portions of the spectrum, the energy level structure can be determined. The amount of shielding for the nucleus of interest depends on its electronic environment, so atoms in different material have different NMR spectra. In practice, the sample is spun in order to avoid strong inhomogeneities. If the solid sample is tilted at the " magic angle " of 54.7°, perturbations from the spinning vanish. The sample is then bombarded with a pulse of radio waves by a transmitter coil, and the emitted intensity is measured as a function of time by the same coil. A fast Fourier transform is then performed on the data to get intensity as a function of frequency. NMR spectra have sharp lines in magnetically homogeneous environments. Typically, " spinning sidebands " are also present, but will be absent is the species being studied is chemically mobile and dynamically free to move randomly. NMR spectroscopy on material thought to be from nearly an impact crater conclusively indicates the presence of stishovite (a high

59. E-NMR.com: Information On Nuclear Magnetic Resonance, X-ray Crystallography Stucture Determination Secondary and tertiary protein structure can be determinedby two methods Xray crystallography and nuclear magnetic resonance. http://www.e-nmr.com/

Healthcare professionals and scientists have carefully prepared this ALtruis Biomedical Network-affiliated site, intended for informational purposes only Partners Stucture Determination Secondary and tertiary protein structure can be determined by two methods: X-ray crystallography and nuclear magnetic resonance. In either case the protein should be better than 95% pure for optimal results. Purification schemes vary but may include gel or column separation, dialysis, differential centrifugation, salting out, or HPLC with the choice and sequence of methods being tailored to the specific protein. Nuclear Magnetic Resonance Nuclear Magnetic Resonance (NMR) spectroscopy has a distinct advantage over X-ray crystallography in that crystallization, which is often difficult and sometimes impossible, is not necessary. State of the art NMR spectroscopy considers 10,000 Dalton molecular weight (MW) structures routine, whereas 20,000 MW structures are far more challenging but have been realized, and even 30,000 MW structures have been partially determined. Technical barriers to NMR spectroscopy are diminishing and prospects are that NMR spectroscopy will eventually resolve protein structures up to 100,000 MW. The greatest advantage of NMR spectroscopy is its facility to reveal details about specific sites of molecules without having to solve their entire structure. Another special advantage of NMR spectroscopy is its sensitivity to motions on the time scale of most chemical events, allowing direct examination of motions on the millisecond to second range and indirect studies of motions on the nanosecond to microsecond range. Modern NMR spectroscopy is particularly adept at revealing how active sites of enzymes work. One technique called Transfer Nuclear Overhauser Spectroscopy (TrNOESY) facilitates shape determination of small molecules bound to very large ones, and helps define the binding pocket of the macromolecule.
