Rayleigh-Brillouin scattering has been employed to study the local structure of polymers in the amorphous state. Measurements of the polarized and depolarized light scattering spectra have been carried out as a function of temperature for several amorphous polymers both above and below Tg. No evidence of long-range orientational order is found. On the contrary, the systems used in this study display only normal liquid like correlations due to packing in a dense medium.
