Generalized coupled oscillator model for defect polymers. I. Calculation of frequency branches of n-paraffins, fatty acids and glymes
No full textNew repeat unit normal coordinates for the analysis of the defect polymer vibrational spectra are suggested. Relations between the valence force field for the GF-Wilson eigenvalue problem and the parameters of the generalized coupled oscillator model involving long-range interactions have been obtained separately for each mode. The results of the application of this model to most modes of finite chains (n-paraffins, fatty acids, and glymes) seem to be quite satisfactory. The applicability of the proposed model is discussed. © 1979
