Research News: The oreintation of polymer molecules has a significant effect on the mechanical properties of polymeric materials. Infrared dichroism spectroscopy is a highly sensitive, chemically specific technique for examining the orientation of the electrical dipole moments in molecules ans as such can be applied to the study of the mechanisms of orientational relaxation in entangled polymer melts. The technique and some of its recent applications are presented.
