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.

✦ Synopsis
A 'H NMR and % ! NMR study of all possible isomers of monoalkylated 3-methylthio-5-amino-1,2,4-triazoles was carried out. The %NMR spectra, including the corresponding proton coupled measurements, proved unambiguously the structures of all derivatives studied.
