## Abstract The ^13^C chemical shift of the substituted or functionalized carbon of various medium and large rings is plotted against ring size (6–15 carbons). The curves thus obtained allow a conformational analysis of the corresponding derivatives.
The steric and electronic interactions in several methanesulphonanilides and dimethane-sulphonanilides have been examined on the basis of their =C NMR chemical shifts. In aromatic amines there is evidence of nitrogen electron pair donation into the aromatic ring. However, the substitution of a metha
