Laser-Excited Raman Scattering in Polystyrene

Abstract
Atactic polystyrene was examined by argon ion laser‐excited Raman scattering. Depolarization measurements of oriented and unoriented polystyrene were made. An analysis is made of the depolarization measurements in terms of the orientation of the sample. Comparisons are made with dichroic measurements made by infrared. Utilizing Raman and infrared polarization data on oriented polystyrene, some changes in band assignments have been made.
