Optical rheometry of multicomponent polymer liquids

Recent advances in optical rheometric techniques are described, and applications of the methods are presented that motivate their use in elucidating the structure and dynamics of complex, polymeric liquids. Spectroscopic methods, such as infrared dichroism and 2-dimensional Raman scattering, which provide information concerning bond-level orientation dynamics are presented. In addition, the combination of birefringence and stress measurements is...
