Abstract/Artist Statement
Nuclear Magnetic Resonance Spectroscopy (NMR) is an instrumental technique to analyze the structures of chemical compounds by measuring their response to electromagnetic radiation while inside a superconducting magnet. Such analysis is performed by an NMR spectrometer. One of the most important components of such a spectrophotometer is the Dewar holding the magnet solenoid. A Varian, Inc. NMR model was used by the University of the Pacific’s chemistry department experiments until 2008. For the purpose of educating students how their NMR spectra are obtained, the magnetic resonance dewar model was cut open to showcase the construction of the vacuum system, the cryogen chambers, the probe, and the magnets. The dewar was cut by Physical Plant on campus and the cross-section will be showcased. In addition, NMR data were collected on the currently active NMR instrument in the Chemistry Department. Spectra and structure of two sugars, isomaltotetraose and gentiobiose, will be presented. The project was made possible by CAPD funding.
