We have examined the nature of the circular dichroism band at 330 mp for a series of copolymers of 8-pnitrobenayl baspartate with @-benay1 baspartate. The circular dichroism band arises from an electronic transition in the nitroaromatic group. I n order to interpret the effect quantitatively, we emp

## Abstract Copolymers of benzylaspartate with the corresponding __para__‐nitro and __ortho__‐nitro derivatives are known to undergo, at increasing nitro content, a transition from a left‐handed α‐helical conformation to a right‐handed α‐helical conformation. The circular dichroism associated with
## Synopsis 111 a study of A-B type block copolymers of y beiizyl-bglutamate arid p-beiizgl-Laspartate use has been made of the observations: ( 1 ) that for pols aspartate esters t.he chemical shifts of the a-CH arid S H resoliarices are sensitive to the helix sense, (2) that in both helical and r
