## Abstract The charge separation between the dithiole ring and oxygen in 3‐(1′,2′‐dithiole‐3′‐ylidene)‐6‐methyl‐2,3‐dihydropyran‐2,4‐diones and 3‐(1′,2′‐dithiole‐3′‐ylidene)‐2,3‐dihydrobenzo[__b__] pyran‐2,4‐diones has been determined by ^13^C and ^19^F n.m.r. spectroscopy. By both methods it is f

## Abstract Characteristic differences in multiplet hyperfine structure observed in coupled ^13^C n.m.r. spectra of symmetrical __o__‐disubstituted benzene rings are explained on general grounds. Contrary to earlier proposals, the observation of this effect in unsymmetrical systems is not a suitabl
## Abstract The 1‐NH structure for 3‐azidoindazole has been demonstrated by the observation of ^1^H^1^H and ^13^C^1^H couplings involving the hydrogen atom attached to nitrogen. A comparison between 3‐azidoindazole and indazole shows that both compounds have the same tautomeric structure.
The iniluence of substituents on the 'H, "C and 15N NMR chemical shifts of 2-substituted 5(6)nitrobenzimidazoles and their analogues labelled with 15N in the nitro group was investigated. It was found that the substituent effects are transmitted to the carbon and hydrogen nuclei in positions 4-7 mai
