Teaching Practice:
Predicting Spectra for Nuclear Magnetic Resonance (NMR)
INTRODUCTION
Nuclear Magnetic Resonance (NMR) spectroscopy is an important part of any organic chemistry course. Students need to learn how to analyze spectra to reveal the molecular structure of compounds. Most students experience difficulty with the concepts, tools and/or process involved with doing the analysis. Each student may have a different mix of difficulties in doing this. Thus, the professor is left to devote a large amount of class time to the mechanics of NMR analysis, traversing the room as students work on problems and stopping to interact with individual students. Even with this attention, some students do not master the basic skills of NMR analysis. Also, this means that there is less class time that can be spent with more profound discussions on the finer points. To address this instructional problem, Dr. Tom Ippoliti and the Center for Multimedia Development at the University of St. Thomas developed a web-based exercise entitled "Predicting Spectra." Through the exercise, students gain experience with a central skill in NMR analysis, namely the ability to predict the characteristics of a spectrum based on a molecular structure. The exercise is adaptive, meaning that students are presented with increasingly more complex problems as they master aspects of the analysis.

The Nuclear Magnetic Resonance Laboratory ( NMRL offers NMR techniques for determining the structure of compounds, the interactions of drug with proteins, cellular pH, in vivo metabolite levels and the metabolic fate of nonradioactive tracers. The sample is placed in an extremely strong magnetic field, irradiated with pulsed radio frequencies and the resultant radio signals are stored, Fourier transformed into a spectrum and analyzed as to the type of chemical grouping, the amount of each, and their linkages to surrounding groups. The measurement is nondestructive. Two NMR spectrometers are available in room E-21 MSB. The 500 MHz spectrometer is broad-banded for studying H-1, C-13, N-15, O-17, F-19, Na-23, P-31, etc. The 360 MHZ spectrometer is for routine analysis of H1, C-13, F-19 and P-31 only. Both spectrometers are connected to the Internet. Data can be processed off-line on our SGI, PC or Macintosh computers or can be transferred to any computer (off-site analysis requires appropriate NMR processing software).

How does a nuclear magnetic resonance machine work?
Nuclear magnetic resonance is used to measure nuclear magnetic moments, the characteristic magnetic behaviour of specific nuclei. Because these values are significantly modified by the immediate chemical environment, however, nuclear magnetic resonance measurements provide information about the molecular structure of various solids and liquids. By the early 1980s nuclear magnetic resonance techniques had begun to be used in medicine. NMR presented a hazard-free, noninvasive way to generate visual images of thin slices of the body by measuring the nuclear magnetic moments of ordinary hydrogen nuclei in the water and lipids (fats) of the body. NMR images show great sensitivity in differentiating between normal tissues and diseased or damaged ones. By the late 1980s NMR had proved superior to most other imaging techniques in providing images of the brain, heart, liver, kidneys, spleen, pancreas, breast, and other organs. NMR provides relatively high-contrast, variable-toned images that can show tumours, blood-starved tissues, and neural plaques resulting from multiple sclerosis. The technique presents no known health hazards, but it cannot be used on patients who have cardiac pacemakers or certain other metal-containing devices implanted in their bodies. Question Number: t00301d This is a stand-alone question which will eventually become integrated into the linked database

Figure 1. Nuclear Magnetic Resonance Absorption apparatus showing major components. SIMPLIFIED THEORY:
If we have a nucleus of magnetic moment mu and nuclear spin I, the relationship between the magnetic moment and angular momentum is: where gamma_N is the nuclear gyromagnetic ratio, g_N is the nuclear "g" factor, and beta_N is the nuclear magneton In a magnetic field H_0, the potential energy of the dipole is: The energy levels for the nuclear dipole in the magnetic field are therefore: where m is the magnetic quantum number which takes the values -I, -I+1, -I+2, ...+I. The separation between levels is g_N beta_N H_0. Since the allowed transitions of the dipole for interactions with electromagnetic radiation are given by deltaI = ± 1, the transition energy, delta E, is also g_N beta_N H_0. The transition frequency is: Now consider a sample containing many such nuclei. Assume that the atoms of the material do not have any permanent electronic magnetic moments. The nuclei of the sample interact with each other only weakly, and even more weakly with the atomic system, termed the "lattice" in this situation, even though it is a liquid or gas. The material to be investigated is immersed in a strong homogeneous magnetic field, H_0. The two sample nuclei, hydrogen (protons) and fluorine, used for this experiment both have non-zero magnetic moments, and a spin of I = 1/2. The randomly oriented spins are aligned by a large magnetic field H_0. The instant H_0 is applied, the nuclei are equally divided between the two quantum states. There is a continual shifting between states caused by thermal energies much larger than E_m that perturb the nuclei through the weak interaction between the magnetic fields of the nuclei and the magnetic fields of the electrons of the atoms of the sample. The effect termed the

Discussion
Nuclear magnetic resonance (NMR) of protons in bulk matter was first demonstrated in 1946 independently by F. Bloch and E. Purcell who were jointly awarded the Nobel prize for their discoveries in 1952. Their original motivation was simply to demonstrate that the feeble magnetism associated with atomic nuclei could be detected in ordinary matter. Their early demonstrations of proton NMR were soon followed by NMR detection of other nuclei and the use of NMR to characterize molecular and solid state environments. Today NMR spectrometers are standard research tools in physics, chemistry, biology, geology, and perhaps most prominently, in medicine for magnetic resonance imaging (MRI) of human tissue. In this experiment you will use a modern 300 MHz Fourier transform NMR spectrometer to (a) study in detail NMR detection techniques, (b) understand the use of NMR for determining molecular structure, and (c) identify the intramolecular coupling between protons in a molecule using homonuclear decoupling techniques. As will become apparent when you browse the list of possible multi-pulse experiments listed in the software menu of the GE GN-300 Omega spectrometer, NMR spectroscopy is a mature scientific field with its own unique jargon, and you will only scratch the surface of possible NMR applications. Excellent introductions to continuous wave (CW) and Fourier transform (FT) NMR techniques can be found in the early chapters of
