Direct linkRen, Jolie; Lin, Tiffany; Sprague, Leonard W.; Peng, Iris; Wang, Li-Qiong – Journal of Chemical Education, 2020
Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

Chemical screening libraries often feature natural product extracts (NPEs) due to the intriguing biological activities they possess and the structural diversity found in their individual components. A research project originally designed to create an extract library of every specimen in the University of Rhode Island (URI) Heber W. Youngken Jr.…

Hopson, Russell; Lee, Po Yin Bowie; Hess, Kathless M. – Journal of Chemical Education, 2018
One dimensional (1-D)[superscript 1] H and [superscript 13]C NMR experiments are common tools used in undergraduate organic laboratories to characterize synthesized molecules. However, 1-D NMR spectra cannot always provide unambiguous structure determination. In research laboratories, advanced NMR spectroscopy methods are employed for structural…
