## Abstract Nitrogen chemical shifts constitute an effective means of distinguishing between isomeric benzazole ring systems. There is a large difference in nitrogen shielding, usually more than 20 ppm, between isomeric benzenoid‐ and quinonoid‐like structures. ^13^C and ^1^H NMR is shown to provid

## Abstract The major protonation sites of six cardiotonic isomeric 2‐aryl‐__n__‐methoxy‐1__H__‐imidazo[4,5‐__b__]‐ and ‐[4,5‐__c__]‐pyridines (n = 4–7) were determined by ^1^H and ^13^C NMR methods. All the 1__H__‐imidazo[4,5‐c]pyridines and the 7‐methoxy derivative of sulmazole were found to prot
## 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
Ab initio molecular orbital calculations have been used to determine the structure of protonated ozone. Four stable minima were found on the 03H+ singlet potential energy surface. Three forms correspond to ozone protonated at the central oxygen ((22") or at the terminal oxygen (two C, isomers, E and
