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
