A comparative study of the 13C chemical shifts and the 'H-13C and 19F-13C coupling constants of N-arylpyrazoles, pyrazolium salts and 2-methyl-and 2-vinylpyrazolium quaternary salts has been carried out. The effect of introducing a substituent at positions 2 and 5 of the pyrazole ring on the conjuga

## Abstract Assignment of the carbon resonances in nine derivatives of __N__‐hydroxybenzotriazole has been carried out. The ^13^C NMR method enables tautomeric __N__‐hydroxy and __N__‐oxide and isomeric __O__‐ and __N__‐acyl structures to be identified. In DMSO, the predominant tautomer of __N__‐hy
Chemical shifts and coupling constants are reported for seven azole derivatives (iidamles, triazoles and their b e m derivatives), their quaternary salts and the corresponding dicyanomethylides. The assignment of the heterocyclic carbons is based on couplings with the N-methyl group. Compared with n
## Abstract The carbon‐13 chemical shifts and the ^1^__J__(CH) coupling constants for 18 azolium salts (di‐__N__‐methyl‐pyrazolium, ‐indazolium, ‐benzimidazolium and ‐benzotriazolium iodides) have been determined and assigned. The chemical shifts are discussed as a function of substituent effects,
## Abstract The ^13^C chemical shifts of 17 indazole derivatives are discussed as a function of substituent effects and the N‐1—H or N‐2—H structure of indazole. The presence in solution of the N‐1—H tautomer is confirmed.
## 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
