Abstract
Spectroscopy is a major analytical tool used to study molecules in all areas of chemistry in industrial and academic settings. Undergraduate students of chemistry need to become well-versed in modern spectroscopic techniques as a preparation for their future careers as chemists. To meet these goals, the Chemistry Department at CSU, Chico has initiated a three-semester advanced integrated laboratory sequence that gives our students research-like experiences doing projects that crossover the major subdisciplines of chemistry. An interdisciplinary project is described that requires students to synthesize conformationally mobile and static α-bromocyclohexanones and to assess, qualitatively and quantitatively, and validate, using several spectroscopic tools, solvent effects on the conformational preferences of these molecules. The project exposes students to a variety of experimental and theoretical techniques that include organic synthesis, product purification, 1H and 13C NMR spectrometry, GC–MS, molecular modeling, and IR and UV spectroscopy.

Adventures in Coaching Young Chemists
Thomas S. Kuntzleman and Bruce W. BaldwinJournal of Chemical Education2011 Article ASAPAdventures in Coaching Young Chemists
Thomas S. Kuntzleman and Bruce W. BaldwinJournal of Chemical Education2011 Article ASAPWe believe that students should have opportunities—early and often—to learn about science and math activities in fun and recreational ways. As a result, we try to provide many science enrichment activities to the surrounding community. In doing so, we ...
