Abstract
The chemical shifts of the methyl groups of 2,4-dimethylbenzo[g]quinoline are defined with respect to concentration, showing that the methyl resonances are reversed from their expected positions in concentrations normally used in NMR spectroscopy. The phenomenon is explained in terms of the probably "fixation" of bonds in the heteroring.
