also obtained for the sparingly soluble substance N-acetylglycyl-L-alaninamide. The results obtained have been used to calculate the pairwise free energy and enthalpy coefficients for the homotactic and heterotactic interactions and these are compared with results obtained earlier on some analogous systems containing the primary amino acid amides. A group-additivity approach has been used to rationalise
