Abstract. The use of state-of-the-art instrumentation in chemistry education continues to expand. For example, Nuclear Magnetic Resonance (NMR) spectroscopy is being introduced in the general chemistry laboratory at some institutions. Some of the challenges associated with widespread use of NMR can be overcome with a new generation of 45 MHz NMR spectrometers. We describe the use of such an instrument with a distillation experiment modified to include NMR analysis of the distillate fractions. The availability of the relatively inexpensive, unintimidating and easy to use spectrometer represents an opportunity for institutions with limited resources to provide students with hands-on experience using NMR.
