Abstract
The dichroic ultraviolet spectra of naphthalene, anthracene, quinoline and acridine have been determined in stretched polyethylene and poly(vinyl alcohol) films. The molecules studied all tend to orient with their long axes along the direction of stretch. However, molecules of essentially identical shape do not necessarily orient to the same extent, nor is the orientation behaviour of a given molecule necessarily identical in the two polymer matrices.Keywords
