The energy radiated back out is at a specific resonance frequency which depends on the strength of the magnetic field and other factors. This allows the observation of specific quantum mechanical magnetic properties of an atomic nucleus . Many scientific techniques exploit NMR phenomena to study molecular physics crystals and non-crystalline materials through NMR spectroscopy . NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI). All stable isotopes that contain an odd number of protons and/or of neutrons (see Isotope ) have an intrinsic magnetic moment and angular momentum , in other words a nonzero spin , while all nuclides with even numbers of both have spin 0.

Nuclear Magnetic Resonance Theory / Background Nuclear magnetic resonance (NMR) was first described independently by Nobel Prize winners Felix Bloch and Edward Mills Purcell in 1946. Purcell had worked on the development and application of RADAR during World War II at MIT, where he focused on the production and detection of electromagnetic radiation radio frequency range (RF ~ 60 MHz). He was specifically interested in the absorption of RF energy by matter. They noticed that magnetic nuclei , like the hydrogen proton, could absorb RF energy when placed in a magnetic field of a strength specific to the identity of the nuclei. When this absorption occurs, the nucleus is described as being in resonance . Interestingly, for analytical scientists, different atoms within a molecule resonate at different frequencies at a given field strength. The observation of the resonance frequencies of a molecule allows a user to discover structural information about the molecule. Thus, like electrons, the protons of certain atoms are considered to have spin . The spinning of these (+ ) charged particles generates a magnetic moment along the axis of spin, so that these nuclei act like tiny bar magnets. Thus, according to quantum mechanics, if a proton is placed in an

Nuclear magnetic resonance (NMR) Nuclear magnetic resonance is an experimental technique of importance in molecular structure elucidation. Macroscopic magnetization and chemical shift The nucleus of an atom might have a spin, or angular moment. Since a spinning charge generates a magnetic field, there is a magnetic moment associated with its moment (Also, the neutron has a magnetic moment). The magnitude of the nuclear magnetic moment is specified in terms of the magnetogyric ratio g pm /Ih, where h is Planck’s constant, m is the magnetic dipole moment and I the spin quantum number. The permitted values of the angular moment are described by the magnetic quantum number m (m = I, (I-1), (I-2),….-I). The H and C nuclei, which are the two most important nuclei in PE, have spin I=½, and therefore only these nuclei will be considered. (In deuteurated polymers H, a spin n = 1 particle may give additional and relevant structure and dynamic information). When a spin I=½ nucleus is placed in a magnetic field, the spin will precess with or against the field direction (B ). The energy of the nucleus depends on the spin direction as shown in Figure 1.

MRC Biomedical NMR Centre Home Facilities Organisation Contact us ... Schedules About The NMR Centre is a multi-user facility for biomedical nuclear magnetic resonance (NMR) which was established by the MRC in 1979. It is located at the National Institute for Medical Research (NIMR) in North London, and has excellent and well-supported facilities for liquid-state NMR studies of biological macromolecules. The Centre's facilities currently consist of three spectrometers, one operating at 800 MHz and two at 600 MHz. The 800 MHz spectrometer and one of the 600 MHz spectrometers are equipped with cryogenically cooled probes. Funding was awarded by the MRC in 2006 for the purchase of a new cryoprobe-equipped 700 MHz spectrometer, to replace an earlier 500 MHz instrument. The new spectrometer became operational in May 2007. Users of the Centre come from NIMR and from universities, colleges and research institutes from all over the UK. The Centre plays an important role in training scientists and PhD students in advanced NMR methods. The location of the Centre within the multidisciplinary Structural Biology environment at NIMR results in significant and mutual benefits for all users of the Centre.

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

Nuclear Magnetic Resonance Spectroscopy 1. Background Over the past fifty years nuclear magnetic resonance spectroscopy, commonly referred to as nmr, has become the preeminent technique for determining the structure of organic compounds. Of all the spectroscopic methods, it is the only one for which a complete analysis and interpretation of the entire spectrum is normally expected. Although larger amounts of sample are needed than for mass spectroscopy, nmr is non-destructive, and with modern instruments good data may be obtained from samples weighing less than a milligram. To be successful in using nmr as an analytical tool, it is necessary to understand the physical principles on which the methods are based The nuclei of many elemental isotopes have a characteristic spin ( I ). Some nuclei have integral spins (e.g. I = 1, 2, 3 ....), some have fractional spins (e.g. I = 1/2, 3/2, 5/2 ....), and a few have no spin, I = (e.g. C, O, S, ....). Isotopes of particular interest and use to organic chemists are H
