content Search SIUC Nuclear Magnetic Resonance Facility The NMR Facility at Southern Illinois University is a university-wide facility. It has three Varian high-field multinuclear spectrometers, an Inova 500, a Mercury plus 400, and an Inova 300 wide-bore. The Inova 300 is usually configured with a 5 mm AutoSwitchable 4-nucleus PFG probe tuned to H, F, C, and P but which can be tuned to other X-nuclei. This instrument also can be configured with broadband probes for 10 mm and 16 mm sample tubes. The Mercury plus 400 is equipped with an AutoX probe with Protune Accessory. Normally tuned to H and C, the probe can be retuned to F and the range of N to P completely by computer control. This spectrometer has higher power amplifiers and higher power Performa II pulsed field gradients. The Inova 500 is generally set up for proton NMR of biological macromolecules. It has 4 RF channels, each with a waveform generator, configured full-band/high-band/low-band/low-band, and the deuterium decoupling accessory is included. The probe usually in position is a PFG H/C/N but other probes are available for X-nuclei (10 mm) when there is a need for maximum sensitivity or resolution. These instruments are available for use by SIUC researchers at attractive rates with discount rates available for extended data collection periods. Facility personnel are available to serve as technicians for an additional $20.00 per hour - otherwise researchers who wish to operate the instruments themselves will be fully trained by the Facility. These rates are designed with the intent that all operating expenses, other than the Director's salary, are recovered.

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). A key feature of NMR is that the resonance frequency of a particular substance is directly proportional to the strength of the applied magnetic field. It is this feature that is exploited in imaging techniques; if a sample is placed in a non-uniform magnetic field then the resonance frequencies of the sample's nuclei depend on where in the field they are located. Since the resolution of the imaging techniques depends on how big the gradient of the field is, many efforts are made to develop more powerful magnets, often using superconductors. The effectiveness of NMR can also be improved using hyperpolarization, and/or using two-dimensional, three-dimensional and higher dimension multi-frequency techniques.

Theoretical principles Introduction Nuclear Magnetic Resonance spectroscopy is a powerful and theoretically complex analytical tool. On this page, we will cover the basic theory behind the technique. It is important to remember that, with NMR, we are performing experiments on the nuclei of atoms, not the electrons. The chemical environment of specific nuclei is deduced from information obtained about the nuclei. Nuclear spin and the splitting of energy levels in a magnetic field Subatomic particles (electrons, protons and neutrons) can be imagined as spinning on their axes. In many atoms (such as C) these spins are paired against each other, such that the nucleus of the atom has no overall spin. However, in some atoms (such as H and C) the nucleus does possess an overall spin. The rules for determining the net spin of a nucleus are as follows; If the number of neutrons and the number of protons are both even, then the nucleus has NO spin. If the number of neutrons plus the number of protons is odd, then the nucleus has a half-integer spin (i.e. 1/2, 3/2, 5/2) If the number of neutrons and the number of protons are both odd, then the nucleus has an integer spin (i.e. 1, 2, 3)

As it turns out, 20% copper and 50% copper seem to have the same specific gravity and conductivity and these are the two alloys that I want to differentiate. It was my understanding that I could apply a strong magnetic field and an RF signal to the metal and measure the power dissipated. As long as the magnetic field and RF frequency were selected so that the nucleii of the copper atoms would resonate, the power disipated by the metal would indicate the amount of copper present. I want to know: Is my understanding of the theory correct? Is there any low cost equipment available to make such measurements? Is there any other potentially low cost technique available for nondestructively measuring the copper content of a silver alloy?

Chapter 13: Spectroscopy Nuclear Magnetic Resonance (NMR) Spectroscopy Basic principles of NMR Chemical shift scale Shielding in H-NMR Table of H-NMR chemical shifts ... C-NMR spectra Basics: Nuclei with an odd mass or odd atomic number have "nuclear spin" (in a similar fashion to the spin of electrons). This includes H and C (but not C). The spins of nuclei are sufficiently different that NMR experiments can be sensitive for only one particular isotope of one particular element. The NMR behaviour of H and C nuclei has been exploited by organic chemist since they provide valuable information that can be used to deduce the structure of organic compounds. These will be the focus of our attention. Since a nucleus is a charged particle in motion, it will develop a magnetic field. H and C have nuclear spins of 1/2 and so they behave in a similar fashion to a simple, tiny bar magnet. In the absence of a magnetic field, these are randomly oriented but when a field is applied they line up parallel to the applied field, either spin aligned or spin opposed. The more highly populated state is the lower energy spin state spin aligned situation. Two schematic representations of these arrangements are shown below: In NMR, EM radiation is used to "flip" the alignment of nuclear spins from the low energy spin aligned state to the higher energy spin opposed state. The energy required for this transition depends on the strength of the applied magnetic field (see below) but in is small and corresponds to the radio frequency range of the EM spectrum.

This phenomenon was first observed in 1946 by the physicists Felix Bloch and Edward M. Purcell independently of each other.

37. Robert G NMR and MRI console electronics can test themselves to a large degree, and such a test has been implemented. http://home.flash.net/~bobgh/nmr.htm

Testing of NMR and MRI Console Electronics (Nuclear Magnetic Resonance and Magnetic Resonance Imaging) Robert Gilchrist Huenemann, M.S.E.E. 120 Harbern Way Hollister CA January 26, 2006 Between 1971 and 1973, I was the principal engineer for the Hewlett-Packard 9540 Transceiver Test System. The 9540 used the then new HP 8660 RF signal generator, and HP was having some difficulty manufacturing this unit. Since the 9540 also included an HP 432 power meter and an HP 5326 frequency counter, I found it advantageous to write an automated test for the 8660, and eventually for other parts of the 9540 system as well. This allowed me to quickly return defective instruments to the various HP manufacturing divisions, with a detailed listing of their failures. Between 1973 and 1980, I was employed in avionics maintenance support at United Airlines. While there, I developed an automated system for recovering VOR (very high frequency omnirange ) bearing angles from the Fourier transform of a digitized VOR signal. These two experiences came together in 1990 when I interviewed for a manufacturing test engineering position at Varian NMRI. It was immediately apparent that NMR and MRI console (and magnet leg) electronics are ideally suited to an automated

Ernst The Nobel Prize in Chemistry 1991 Summary Press Release Illustrated Information ... Other Resources Autobiography I was born 1933 in Winterthur, Switzerland, where our ancestors resided at least since the 15th century. We lived in a home built in 1898 by my grandfather, a merchant. My father, Robert Ernst, was teaching as an architect at the technical high school of our city. I had the great luck to grow up, together with two sisters, in a town that combined in a unique way artistic and industrious activities. Invaluable art collections and a small but first rank symphony orchestra carry the fame of Winterthur far across the borders of Switzerland. On the other hand, industries producing heavy machinery, like Diesel motors and railway engines, provided the commercial basis of prosperity. I thus decided to leave the university forever and tried to find an industrial job in the United States. Among numerous offers, I decided for Varian Associates in Palo Alto where famous scientists, like Weston A. Anderson, Ray Freeman, Jim Hyde, Martin Packard, and Harry Weaver, were working
