Ringing in Volume 94
The January 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: NMR spectroscopy; examining assessment; inquiry-based practices; cost-effective instrumentation; miscibility demonstrations; innovative laboratory experiments; from the archives: lightsticks.
To kick off the new volume, Editor-in-Chief Norbert J. Pienta muses on How To Make a Journal Better.
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.
