Extractions: 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. 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)

Extractions: NMR is a unique tool that allows researchers to determine the the three dimensional structure of molecules. With increasing interest in the structure of biochemical molecules (such as proteins), NMR spectrometers are rapidly becoming key enabling tools for drug discovery, DNA analysis, and human genomic studies. A related technique known as NMR imaging uses much of the same instrumentation to perform research on how the brain and other organs work and react to various stimuli.

Extractions: 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

NMR has found key uses in chemical research, biochemistry, pharmaceutical chemistry, polymer science, petroleum research, agricultural chemistry, and medicine. The NMR signal is a natural physical property of the certain atomic nuclei but it can only be detected with an external magnetic field. Most modern NMR spectrometers utilize a magnet fabricated from superconducting materials and the magnet winding is cooled with liquid helium. The sample for NMR analysis remains at room temperature. Each isotope of each element in the Periodic Table has a different NMR signal frequency. The most commonly observed nucleus is hydrogen (1H) as found in water (H2O), although the NMR signal from many other nuclei can be observed with the appropriate hardware. The NMR signal for most spectrometers is in the radio frequency part of the electromagnetic energy spectrum and NMR spectrometers are referred to by the proton NMR frequency, e.g. 60MHz, 300MHz or 500MHz. In most high-field superconducting magnet NMR systems, the radio frequency (RF) signal is "pulsed" in short bursts thus the name "Pulsed" NMR. Alternatively, the NMR signal can be observed by sweeping the magnetic field with continuous RF, thus the name "Continuous Wave" NMR or "CW" NMR. Continuous wave NMR is usually found on low-field permanent magnet NMR spectrometers. Pulsed NMR systems can do many more types of NMR experiments than CW NMR systems, however the pulsed NMR signal must be processed on a computer with a Fourier Transform (FT) to be interpreted, thus the name "FT NMR." Transforms other than the Fourier Transform can also be used.

Extractions: deutsch Principle of NMR Turning the measurement of a magnetic field into a measurement of the frequency The DRUSCH NMR Gaussmeter carries out measurements of the magnetic field strength following the principle of nuclear magnetic resonance. The method is based on the quantisation of the spin alignment in a magnetic field. For example the proton spin (spin 1/2) can be aligned parallel or anti-parallel to the magnetic field. According to the alignment of the spin there is an additional potential energy term Where denotes the magnetic field. As the alignment of the nuclear spin is quantised there is a discrete set of additional energy levels E i the nucleus can occupy for a certain magnetic field. Thus, the energy states of particles with spin 1/2, like the proton, which have opposed spin alignment differ by: The energy state of the nucleus can be altered by an external electromagnetic force, for example by an resonant circuit. The interaction between the nucleus and the source of the external force is mediated by the photon, the quantum of the electromagnetic interaction. As the energy level of the nucleus is quantised a nucleus with the initial energy E i can only absorb or emit photons of the energy: A proton for example can only emit or absorb photons of the energy: According to Planck this corresponds to an electromagnetic wave of the frequ ency: where h is Planck's constant. This frequency is called
