## 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 hetero
N NMR spectroscopy was used to extend previous studies, by "C NMR and IR spectroscopy, of fused oxoheterocycles which contain the guanidine unit. These compounds fall into three clearly definable structural types, through-conjugated, ring-conjugated or imide-like, any or all of which may result from
13C and "N NMR spectroscopic assignments are given for a series of N-aryl-N-cyanoguanidines in DMSO-d, along with those for a few related cyanoguanidines. The NMR data are interpreted in terms of minimal overlap of the amino lone pair with the attached aryl ring, and a planar guanidine structure wit
