Abstract

A newly-designed problem-based laboratory experiment utilizing a benchtop NMR spectrometer was implemented for undergraduate students. The aim of the experiment was to have a hands-on, problem-based approach that focused on structure elucidation as well as practical aspects such as sample preparation, data acquisition and manipulation. The experimental protocol also allowed the students to understand other aspects of NMR spectroscopy such as identification of impurities and its application in monitoring reaction progress. Results from a survey and a quiz conducted as part of the study clearly indicated that this hands-on approach not only helped to reinforce the theory learned in a lecture course, but also allow the students to realize the full potential of this important spectroscopic technique.
