NMR (Nuclear Magnetic Resonance) Scans of Mountain Dew This spectrum is a H NMR of Mt Dew in D O. The water peak at 4.8 ppm has been removed. This spectrum is the C NMR of Mt Dew in D O. (Technical info: The sample was prepared by rotovaping ~20 ml of Mt Dew down to syrup, and then placing two drops in ~2 ml of D O. The spectrum was run at 300MHz, with 16 acquisitions, a pulse angle of 30 degrees, and a relaxation delay of 1 second.)

37. DRUSCH Principle Of Nuclear Magnetic Resonance Turning a measurement of the magnetic field strength into a frequency measurement (NMR gaussmeter) http://www.drusch.com/help/qmpr.html

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

NMR Spectroscopy 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
