Resonance interaction of the carbonyl vibrations for model collagen structure [(PRO-PRO-GLY)10]3 have been treated on the basis of molecular exciton theory in a dipole-dipole approximation. The frequency shifts of the carbonyl vibrations induced by dipole coupling, inter-peptide and peptide-water hydrogen bond formation were obtained. The relative contributions of energies of peptide-water and inter-peptide hydrogen bonds and energies of other types of interaction to the total stabilization energy were estimated for the model collagen structures.
