## Abstract The rotational barrier in the __N__,__N__‐dimethylamide group is studied by proton NMR for __N__,__N__‐dimethylnicotinamide and two quaternary salts in aqueous solution. The carbon‐13 NMR spectra of a number of aromatic __N__,__N__‐dimethylamides are discussed. A roughly linear correlat
