Abstract
The chemical shift of an aromatic proton adjacent to a nitro group is sensitive to the degree of coplanarity between the nitro group and the aromatic ring, and variations in the chemical shift have been used to examine the configurations of N-methyl and NN-dimethylanilines bearing o-nitro substituents.
