Teaching the Fundamentals of Pulsed NMR Spectroscopy in an Undergraduate Physical Chemistry Laboratory

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.
Supplement
The step-by-step experimental procedures for this laboratory are described in detail.
