Abstract
Recent advances in NMR spectroscopy allow one to study extremely dilute systems or nuclei which occur in low natural abundance and/or have poor sensitivity for NMR detection. This paper describes various pulse and pulse Fourier transform NMR techniques. Included in this introduction are: (1) a brief review of the nuclear relaxation phenomenon, (2) sensitivity enhancement using the pulse technique, (3) pulse instrumentation, and (4) the analytical applications of pulse Fourier transform NMR.
