Detailed Raman scattering data on brominated (SN)x crystals ranging in composition from (SNBr0.27)x to (SNBr0.55)x, and preliminary Raman data on [SN(ICI)0.125]x are discussed. The investigation involved a study under various conditions of temperature, pressure and levels of bromination, of the two primary Raman lines at 154 and 230 cm-1 in brominated (SN)x, which are polarized along the polymer axis direction. The analysis of the data is consistent with a model in which bromine enters the interfibrillar regions as Br-3 and the (SN)x lattice as Br2. Infrared data is also presented showing an appreciable decrease in intensity of the SN modes at 995 and 670 cm-1 on bromination.
