Abstract

Raman spectra of poly(Gly-Pro-Pro) and type I collagen in deuterium oxide solution were obtained. Frequencies of type A stretching carbonyl vibrations were calculated according to the model of weakly connected oscillators within the limits of theory of perturbations for polypeptide structures taking into consideration the dynamic resonance interactions of transition dipoles. The calculated frequencies agree with the experimental frequencies of the Amide I band in Raman spectra of poly(Gly-Pro-Pro) and type I collagen.
