1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.

N NMR chemical shifts were measured for a series of substituted 5-amino-1,2,4-triazoles. The assignment of isomeric structures agrees with earlier results obtained with the use of proton-coupled I3C NMR.
## Abstract The ^1^H and ^13^C NMR spectra of some novel 1,2,4βtriazolo [1,3] thiazinoquinoline isomeric pairs are interpreted in terms of structural assignments. The structure of most compounds has been confirmed by NOE difference spectroscopy. Characteristic differences have been observed in both
Quantitative evaluations of the percentages of rotational isomers in 1-vinyl-l, Z 4-triazoles were obtained. The population of the s.cis(N(2)) form in 1-vinyl-l,2,4-triazole is greater by a factor of two than in the s-trans form. ## Quantitative evaluations of the percentages of the rotational isom
