The recent isolation of pyrazines from various natural sources ( ) has stimulated interest in the characterisation of this class of compound.(2) For simple di-and trisubstituted pyrazines the main problem of structure elucidation is often the determination of the relative positions of the substituen

## Abstract The 1βNH structure for 3βazidoindazole has been demonstrated by the observation of ^1^Hο£Ώ^1^H and ^13^Cο£Ώ^1^H couplings involving the hydrogen atom attached to nitrogen. A comparison between 3βazidoindazole and indazole shows that both compounds have the same tautomeric structure.
