摘要：

N-15, N-14, C-13 and H-1 NMR data were used for the structural analysis of seven 1,2,3,4-thiatriazoles with various exocyclic groups. Measurements at various temperatures were carried out in order to study the behaviour of exocyclic groups. Some N-15-labelled compounds were prepared to assist in the interpretation of the N-15 NMR spectra. The results suggest that the investigated compounds exist in the cyclic structure. Three of the investigated compounds have not been previously synthesized.
