## Abstract The free energy of activation for rotation about the exocyclic CN 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
## Abstract The barriers to rotation about the C(O)N bond for 13 α‐alkyl‐ and α‐halo‐substituted __N__‐theyl‐__N__‐methylamides were determined by ^1^H NMR spectroscopy at coalescence temperature. Plots of Gibbs free energy (Δ__G__°) and Gibbs energy of activation (Δ__G__‡) values against Charton'
