Cover: NMR Spectroscopy

Nuclear magnetic resonance (NMR) spectroscopy plays an integral role in the chemistry curriculum, spanning theory, concepts, and experimentation; it is imperative that the instruction methods for NMR are both efficient and effective. The cover features the laboratory experiment, Rapid Determination of Enantiomeric Excess via NMR Spectroscopy: A Research-Informed Experiment. John S. Fossey, Eric V. Anslyn, William D. G. Brittain, Steven D. Bull, Brette M. Chapin, Cécile S. Le Duff, Tony D. James, Glenn Lees, Stephanie Lim, Jennifer A. C. Lloyd, Charles V. Manville, Daniel T. Payne, and Kimberley A. Roper describe an experiment that exploits chiral supramolecular assemblies for the determination of enantiomeric excess by 1H NMR spectroscopy.  (This article is available to non-subscribers as part of ACS’s AuthorChoice program.)
