Coupling between two local amide I vibrational motions in glycine dipeptides was studied. The analysis was based on the assumption that the two peptides interact with each other via transition dipole coupling (TDC) model. It was found that the model was capable in quantitatively calculating spectroscopic properties like dipole moments, molecular polarizability, IR transition dipoles and intensity. Results also showed that the quantities related to the potential energy surfaces could not be accounted by TDC model.
