Visible dichroism can be utilized as a measure of the degree of orientation of an amorphous region in a polymer. But the relations between dichroism and states of dyes in polymer must be elucidated before dichroism can be used more widely as a reliable means for study of amorphous orientation. To ca
## Abstract Expressions are derived to relate the linear dichroism of oriented helical and superβhelical polymers to the vector equation describing a transition moment in a reference frame based on the position of a single monomer unit in a simple helix and the superβhelix tilt angle Ξ². The reduced
