Abstract

Pulsed nuclear magnetic resonance (NMR) spectroscopy has become the premiere technique for chemists and biochemists studying the conformational, structural, and dynamic properties of a wide variety of molecular and biological systems. The theories and physical concepts associated with pulsed NMR spectroscopy are difficult for undergraduate students to comprehend and often require a thorough understanding of spin physics. Additionally, undergraduates in a laboratory course often consider a pulsed NMR spectrometer to be a "black box" and do not really understand how it operates. To address these issues, we developed an undergraduate physical chemistry laboratory experiment that utilizes a commercially available bench-top pulsed NMR spectrometer. In this experiment, the students assemble the components of an NMR spectrometer, program a variety of pulse sequences, and collect T₁ and T₂ relaxation data.
