Debbert, Stefan L.; Hoh, Bradley D.; Dulak, David J. – Journal of Chemical Education, 2016
In this experiment for an introductory undergraduate organic chemistry lab, students tetraalkylate tertbutylcalix[4]arene, a bowl-shaped macrocyclic oligophenol, and examine the supramolecular chemistry of the tetraether product by proton nuclear magnetic resonance (NMR) spectroscopy. Complexation with a sodium ion reduces the conformational…

Ryan, Michael D.; Reid, Scott A. – Journal of Chemical Education, 2016
Despite much recent interest in the flipped classroom, quantitative studies are slowly emerging, particularly in the sciences. We report a year-long parallel controlled study of the flipped classroom in a second-term general chemistry course. The flipped course was piloted in the off-semester course in Fall 2014, and the availability of the…

Walter Kerby, Holly; DeKorver, Brittland K.; Cantor, Joanne; Weiland, Marcia J.; Babiarz, Christopher L. – Journal of Chemical Education, 2016
Demonstration shows are a widely used form of Informal Science Education. While there is evidence that the shows are highly enjoyable, little work has been done to investigate the cognitive impacts of these shows. This article describes the development and production of "The Boiling Point," a show that uses the structure of a play to…

Litofsky, Joshua; Viswanathan, Rama – Journal of Chemical Education, 2015
Matrix diagonalization, the key technique at the heart of modern computational chemistry for the numerical solution of the Schrödinger equation, can be easily introduced in the physical chemistry curriculum in a pedagogical context using simple Hückel molecular orbital theory for p bonding in molecules. We present details and results of…

Bonjour, Jessica L.; Pitzer, Joy M.; Frost, John A. – Journal of Chemical Education, 2015
Mole to gram conversions, density, and percent composition are fundamental concepts in first year chemistry at the high school or undergraduate level; however, students often find it difficult to engage with these concepts. We present a simple laboratory experiment utilizing portable nuclear magnetic resonance spectroscopy (NMR) to determine the…

Teplukhin, Alexander; Babikov, Dmitri – Journal of Chemical Education, 2015
In our three-dimensional world, one can plot, see, and comprehend a function of two variables at most, V(x,y). One cannot plot a function of three or more variables. For this reason, visualization of the potential energy function in its full dimensionality is impossible even for the smallest polyatomic molecules, such as triatomics. This creates…
