Vibrational dynamics of gamma form of nylon 6 (γNY6)



Normal mode analyses including phonon dispersion have been performed, to understand completely the spectra (Infrared/Raman) of (γNY6), using Wilson GF matrix method and Urey-Bradley force field. Characteristic features of the dispersion curves such as repulsion and region of high density-of-states have been explained. Heat capacity measurements have been interpreted and the limitation of this work discussed. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
