Nuclear Magnetic Resonance Spectroscopy (NMR) The nuclei of some atoms, but not all, behave as if they were rotating, or spinning, about an axis passed through them, much as a top spins about its central axis. This is quite easily visualized in terms of the particle nature of the nucleus; it is less easily visualized in terms of the wave picture, which by now we know is another face of nature that is manifested in the atomic/molecular realm. Spin of nuclei is similar to electron spin. Examples of atoms whose nuclei spin are hydrogen, fluorine, the 13 isotope of carbon, and the 15 isotope of nitrogen. There are many others that will not be listed here. The focus in this chapter will be on the spin of the hydrogen nucleus, because hydrogen atoms occur very frequently in molecules and are therefore very useful in determination of structure. When placed in a strong magnetic field, the spinning motion of the hydrogen atom gives rise to two energy levels. These are shown in an energy level diagram in Figure 1 The spin can be promoted from the lower to the higher level by interacting with and absorbing energy from electromagnetic radiation in the radio frequency (RF) region of the spectrum. A typical radio photon has a frequency of 10

Southern IllinoisUniversity Nuclear Magnetic Resonance Facility The NMR Facility at Southern Illinois University is a university-wide facility, supported by the Office of Research Development and Administration , the School of Medicine , and the College of Science It has two high-field multinuclear spectrometers, a Varian VXR-300 (proton at 300 MHz)system with an Oxford wide-bore magnet, and a Varian Inova-500 (proton at 500 MHz) standard bore system. The VXR-300 is usually configured with a 5 mm broadband switchable probe tuned to H and C. Macro-driven software allows execution of routine proton, carbon, APT, DEPT, COSY, and heteronuclear correlation experiments after only minimal time investment in training. This instrument also can be configured with a sensitive 5 mm proton/fluorine probe or broadband probes for 10 mm and 16 mm sample tubes. The Inova-500 is generally set up for proton NMR of biological macromolecules but it can be set up 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.

Nuclear Magnetic Resonance Quantum Computing (NMRQC) What is Quantum Computing? Quantum Computing is a fundamentally new paradigm for information processing, harnessing the power of quantum mechanics. How does it differ from classical computation? It differs from classical computation (your desktop) by being able to perform massive parallel computations. What can we do with a quantum computer? Secure communication Search unsorted data bases faster than classical computers Factor integer numbers faster Simulating quantum mechanical systems efficiently. Introduction to Classical Information Theory Let us quickly review some classical concepts of information theory. Information is real and physical and can thus be represented by physical systems: For example, in your computer, wires can be at or 5 Volts with respect to some reference, representing the binary numbers or 1. We can compute by taking many of these wires as inputs to some configuration of transistors, and in the end we measure the voltage on the output wires and translate it to an answer. This method of computing is very common but not unique! Note that your brain can multiply or add (small) numbers without paper and pen – Similarly, the abacus has been used extensively before our ‘electronic’ computers – or we could even use billiard balls! In fact, it does not matter how information is represented! If I were to give you a black box capable of computing, you would not be able to tell how exactly information is processed! This allows us to use the common notion of a

The Centre is a multi-user facility for biomedical nuclear magnetic resonance (NMR) which was set up by the MRC in 1980. It is located at the National Institute for Medical Research ( NIMR ) and has excellent and well-supported facilities for liquid-state NMR studies of biological macromolecules. The Centre's facilities include spectrometers operating at 800, 600 and 500 MHz. Funding has recently been awarded for a 600MHz cryogenically cooled probe and a replacement console. The 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.

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)

NDT.net - May 2001, Vol. 6 No. 5 Ultrasound, Scanning Electron Microscopy and Nuclear Magnetic Resonance Spectroscopy - Comparison of Results Investigating the Hydration Process in Cementitious Materials Christian U. Grosse, Stephanie U. Köble, Hans W. Reinhardt Corresponding Author Contact: Email: reinhardt@iwb.uni-stuttgart.de , Web: http://www.iwb.uni-stuttgart.de SUMMARY When measuring mortar or other cementitious materials with ultrasound the question arises whether the results of the non-destructive measurements are coherent with visual parameters describing the hydration process in the material. Special microscopic techniques are difficult to apply due to the interaction between the method (for example evacuation) and the material. First results are presented describing the use of the scanning electron microscopy (SEM) and the nuclear magnetic resonance spectroscopy (NMR spectroscopy) investigating mortar or cement paste and calorimeter measurement of hydration temperatures in comparison to results of ultrasonic measurement techniques developed by the authors.

Facilities: The Center has a low field 2 MHz Resonance Instruments Maran 2 spectrometer with gradient capability along the z-axis. This is the standard apparatus used to support NMR wireline log interpretation with NMR relaxation measurements on one-inch diameter core plugs. We have added a non-proton heat exchanger system for measurements at elevated (reservoir) temperatures. We have a plastic NMR cell for live fluids at up to 4000 psig pressure. The ADC front-end on the Varian INOVA imager has a fast 0.5 MHz bandwidth that is 5x faster than the standard medical imager. Moreover, the machine has been upgraded with state-of-the-art quadrature birdcage rf coils and chemical-shift, diffusion, backplane reconstruction and other specialty pulse sequences. These modifications make the instrument ideal for advanced imaging of materials and the determination of cellular structures. Our lab has excellent supporting test and measurement electronics and computers and a Luxtron fluoroptic thermometer, which works without interference in strong rf and magnetic fields. The Center uses a Bartington MS-2 magnetic susceptibility instrument and an APS fluxgate magnetometer to characterize its core samples.
