Multiple uses of UV-Vis, IR, and NMR in the general chemistry program

Curtis R. Pulliam and William F. Pfeiffer. Utica College, Utica, NY

We have been using IR and NMR in our general chemistry program for over 10 years as a way for our students gather and use information relating to molecular structure. We are currently having our students use visible spectroscopy in three quantitative experiments, IR twice and carbon-13 NMR in two different experiments. In some of these experiments the use of instrumentation is fundamental to the analysis (copper in brass), in others they are additions to commonly done experiments (aspirin synthesis and the determination of the identity of an unknown organic acid), and some are totally new experiments we have developed (such as a discovery activity about NMR). Using an instrument multiple times allows students to have one experience concentrating on what kind of information can be gathered and how to analyze that information, and another experience seeing how the instrument can help them solve problems relating to molecular structure or purity. We will describe these laboratory activities and discuss logistics of using these instruments in the general lab. The IR and NMR were purchased using NSF ILI grants (IR USE-8851770; NMR DUE-9351955). The Camille and Henry Dreyfus Foundation supported the NMR purchase.
