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.
