## Abstract The free energy of activation for rotation about the exocyclic CN bond of the dimethylamino group of some 6‐substituted 2‐amino‐4‐(__N__,__N__‐dimethylamino)pyrmidines has been determined using ^1^H NMR line shape analysis. The results are discussed in terms of the relative electron‐wi
