Although the subject of numerous investigations, the origins of 13C nmr chemical shifts are still not well understood.a In order to simplify the problem, we have examined a wide variety of halogen substituted (F,Cl,Br,I) compounds. The similarity of the C-X bond dipoles" should minimize contribution
## 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,
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 Evaluation by empirically derived equations for the substituent effect (α, β, γ, δ) on the ^13^C NMR chemical shifts for C‐3, C‐4, C‐5 and halomethyl‐substituent carbon (C‐6) in 5‐halomethyl‐5‐hydroxy‐4,5‐dihydroisoxazoles (where C‐3 substituent=H), alkyl or phenyl, C‐4 substituent=H, a
