There is much interest in examining the structure of sulfur compounds because of the role of sulfur as a principal contributor to environmental pollution. By a pulsed NMR technique, the extremely weak free induction decay signal of 33S in several liquid compounds was detected. Using the relatively easy to detect carbon disulfide resonance as a reference model, a method is discussed for studying sulfur compounds which takes into consideration the symmetry and spin relaxation parameters (T1 and T2). Consideration is given to the instrumental parameters which can be varied to enhance 33S pulsed NMR resonances.
