Nuclear magnetic resonance (NMR) spectroscopy is one of the most widely used characterization techniques in chemistry. Despite pedagogical shifts towards active-learning and guided-inquiry approaches, incorporation of NMR spectrometers directly into undergraduate curricula have remained largely limited due to mitigating factors such as size, cost, and availability of high-field spectrometers. <br/> <br/>The emergence of permanent magnet-based benchtop NMR spectrometers promises a way to address affordability, maintenance, and ease-of-use concerns. However, one of the well-known trade-offs in lower field proton NMR spectroscopy is the reduced chemical shift dispersion. In this presentation, we detail results of benchtop NMR applications involving heteronuclides, such as <sup>31</sup>P, where the larger chemical shift ranges permit novel applications.
