Description
Summary:A detailed study was performed to investigate the normal modes of vibration and their dispersions in poly (vinyl butyral) by using Urey-Bradley force field and Wilson’s GF matrix method as modified by Higgs. It provides detailed interpretation of FTIR. Characteristic feature of dispersion curves such as regions of high density–of–states, repulsion and character mixing of dispersion modes are discussed. Predictive values of heat capacity as a function of temperature between 0-350 K have been evaluated.
