Proton magnetic resonance spectra of model dipeptide molecules R1-C;O~-N~H~-C;H$R~-C~O~-N~HR-R~ in CC14 solutions exhibit splited signals when investigating on mixtures of L and D enantiomers differing from the racemic composition. The major effect is observed on amide proton signals which are the o
