Abstract

Abstract The unambiguous discrimination between signals due to H-3 and H-5 in various 1-substituted 1H-1,2,4-triazoles as well as the differentiation between isomeric 1,3-, 1,5- and 3,4-disubstituted 1,2,4-triazoles by means of NOE difference spectroscopy is described. The assignments based on NOE difference experiments are shown to agree with those resting on triazole-13C,1H spin-coupling constants.
