Over the past few years, NMR spectroscopy has become an increasingly important tool in undergraduate education because of its value in structure determination. Two major goals at many colleges and universities is to introduce NMR early in the chemistry curriculum and give students an opportunity to take full advantage of the technique in both classroom and research activities. This can be challenging due to the sizable enrollments of many introductory chemistry classes and their limited laboratory time. In addition, the use of expensive and hazardous NMR solvents (e.g., chloroform-d, D2O, etc.) can often discourage professors from conducting NMR analyses with beginning students. Experiments that incorporate medium field FT-NMR in large undergraduate classes are described. 1H-decoupled, 13C NMR spectroscopy is used in general chemistry and organic chemistry. Neat samples are used to acquire large numbers of NMR spectra. This facilitates sample preparation and accelerates data acquisition processes.
