Nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique in the organic chemistry laboratory for elucidation of molecular structure. Miniaturization of NMR technology has attracted attention and acceptance due to a considerable reduction in the cost to acquire and maintain the instrument. The advent of low-field, low-cost, and low-maintenance tabletop NMR technology has provided academic institutions with limited resources the option of hands-on NMR experimentation for undergraduates. The application of the tabletop NMR instrument in the organic chemistry laboratory to analyze an unknown liquid, which can be an ester, an aldehyde, an alcohol, or a ketone, together with infrared (IR) spectroscopy and classic chemical color tests, is herein described.
