Abstract

The ^15^N chemical shifts and ^1^H^15^N and ^13^C^15^N coupling constants of nine monolabelled indazoles were measured and assigned. The experimental values are discussed in terms of the indazolic and iso‐indazolic structures, and compared with literature data for other related heterocycles. All the results are consistent with an N‐1(H) tautomeric structure for indazole in DMSO‐d~6~.

C and 15 N NMR data are reported for nine azoloazines. From the results obtained it is found that the 15 N chemical shifts are particularly well placed to provide reliable data on both the structures of the compounds studied and on their potential to undergo valence and prototropic tautomerism. Of p
