The potential power and utility of 15N NMR spectroscopy in heterocyclic chemistry is illustrated by the natural-abundance high-resolution 15N NMR spectra of representative thiadiazoles and related compounds. The 15N chemical shifts in these compounds were found to range over 250 ppm. The advantages and limitations of the method are discussed.
