N-alkyl-N-1-naphthylformamides has been measured in a series of solvents using NMR spectroscopy. A linear relationship was found between the free energy of the conformationalequilibrium, ΔG0, and the relative dielectric permittivity of the solvent. The comparison of NMR data with quantum-chemically calculated SCRF heats of equilibria reveals that the solvent effect is a combination of both the electrostatic and
