43. Nuclear Magnetic Resonance nuclear magnetic resonance. When the nuclear magnetic with the spin flip. This process is called nuclear magnetic resonance (NMR). http://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/nmr.html

Nuclear Magnetic Resonance When the nuclear magnetic moment associated with a nuclear spin is placed in an external magnetic field, the different spin states are given different magnetic potential energies . In the presence of the static magnetic field which produces a small amount of spin polarization , a radio frequency signal of the proper frequency can induce a transition between spin states. This "spin flip" places some of the spins in their higher energy state. If the radio frequency signal is then switched off, the relaxation of the spins back to the lower state produces a measurable amount of RF signal at the resonant frequency associated with the spin flip. This process is called Nuclear Magnetic Resonance (NMR). A magnetic dipole moment (usually just called " magnetic moment ") in a magnetic field will have a potential energy related to its orientation with respect to that field. Note that the electron spin magnetic moment is opposite to the electron spin while the proton spin magnetic moment is in the direction of the proton spin. The electron spin or proton spin will tend to precess around the magnetic field with a frequency traditionally called the Larmor frequency . For a 1 Tesla magnetic field this Larmor frequency would be The Larmor frequency can be visualized classically in terms of the precession of the magnetic moment around the magnetic field, analogous to the

49. The History Of Magnetic Resonance Imaging (page 1) The first successful nuclear magnetic resonance (NMR) experiment was made in 1946 independently by two scientists in the United States. http://www.isbe.man.ac.uk/personal/dellard/dje/history_mri/history of mri.htm

Magnetic resonance imaging (MRI) has become the primary technique throughout the body in the routine diagnosis of many disease processes, replacing and sometimes surpassing computed tomography (CT). MRI has particular advantages in that it is non-invasive, using non-ionising radiation, and has a high soft-tissue resolution and discrimination in any imaging plane. It may also provide both morphological and functional information. The resultant MR image is based on multiple tissue parameters any of which can modify tissue contrast. In its development, MRI has incorporated a multidisciplinary team of radiologists, technicians, clinicians and scientists who have made, and are continuing to make, combined efforts in further extending the clinical usefulness and effectiveness of this technique. The first successful nuclear magnetic resonance (NMR) experiment was made in 1946 independently by two scientists in the United States. Interestingly, Dr Isidor Rabi, an American physicist who was awarded the Nobel Prize for Physics in 1944 for his invention of the atomic and molecular beam magnetic resonance method of observing atomic spectra, came across the NMR experiment in the late 1930's but considered it to be an artefact of his apparatus and disregarded its importance. During the 50's and 60's NMR spectroscopy became a widely used technique for the non-destructive analysis of small samples. Many of its applications were at the microscopic level using small (a few centimetres) bore high field magnets.

Main Page See live article Alphabetical index Nuclear magnetic resonance Nuclear magnetic resonance NMR ) is a physical phenomenon described independently by Felix Bloch and Edward Mills 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 magnetic field. An antenna (usually a coil-shaped inductor with the sample inside) is used to irradiate the sample with radio waves. At certain frequencies, atomic nuclei within the sample will absorb the radiation and enter an excited state. After a time, the nuclei will re-emit the radiation, which can be detected by the antenna. Finally, a measurement is taken of how much radiation is re-emitted, and when. Only nuclei with non zero magnetic moment can undergo NMR. Such nuclei must have an odd number of

55. Proton Nuclear Magnetic Resonance Proton nuclear magnetic resonance. keywords equivalent hydrogens neighboring hydrogens peak splitting singlet doublet triplet http://web.umr.edu/~wlf/Spectroscopy/protonNMR.html

Proton Nuclear Magnetic Resonance keywords: [equivalent hydrogens] [neighboring hydrogens] [peak splitting] [singlet] [doublet] [triplet] [peak integration] [chemical shift or downfield shift] [delta values] A full NMR has spike peaks rising up from the baseline along the bottom. Find a spectrum that has the spikes and also curvy lines above the spikes. Those curves drawn above the spikes are the result of integration over peak area. Notice that the spikes are in groups. Three spikes equally spaced apart are called a triplet, and actually should be thought of as one peak. one spike = singlet two spikes = doublet four = quartet There are four pieces of information on an NMR spectrum you need to use: the number of peaks, peak splitting (singlet, doublet, etc.) peak integration peak location. These will be discussed shortly, but first you must be able to recognize equivalent hydrogens In this monograph NMR refers to proton NMR. Here the instrument is set up to deal with hydrogens. A peak shows up as the result of a hydrogen feeling the presence of hydrogens one carbon away (adjacent hydrogens is a more precise term). For example, the hydrogens on the second carbon of pentane will be influenced by the hydrogens on the first and third carbons, and hydrogens on the third will be influenced by the hydrogens on the second and the fourth and so on. Hydrogens one carbon away are called "neighboring hydrogens".

58. Nuclear Magnetic Resonance nuclear magnetic resonance,. nuclear magnetic resonance is used to measure nuclear magnetic moments, the characteristic magnetic behaviour of specific nuclei. http://www.britannica.com/nobel/micro/431_70.html

nuclear magnetic resonance, abbreviation NMR, selective absorption of very high-frequency radio waves by certain atomic nuclei that are subjected to an appropriately strong stationary magnetic field. This phenomenon was first observed in 1946 by the physicists Felix Bloch and Edward M. Purcell independently of each other. Nuclei in which at least one proton or one neutron is unpaired act like tiny magnets, and a strong magnetic field exerts a force that causes them to precess in somewhat the same way that the axes of spinning tops trace out cone-shaped surfaces while they precess in the Earth's gravitational field. 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 from the radio wave. This selective absorption, called resonance, may be produced either by tuning the natural frequency of the nuclear magnets to that of a weak radio wave of fixed frequency or by tuning the frequency of the weak radio wave to that of the nuclear magnets (determined by the strong constant external magnetic field). See also magnetic resonance Nuclear magnetic resonance is used to measure nuclear magnetic moments, the characteristic magnetic behaviour of specific nuclei. Because these values are significantly modified by the immediate chemical environment, however, NMR measurements provide information about the molecular structure of various solids and liquids.
