✦ Synopsis

Poly(7-p-chlorobenzyl cglutamate), for which theoretical calculations have shown only a small difference in energy between the left-and right-handed a-helices, has been synthesized and its screw sense determined by ORD in various solvents. In all solvents studied, a right-handed a-helix has been observed.

In this paper two points are considered: the methods of evaluating the helical content 8 and the calculation of the parameters of the transition from experimental data and its interpretation. The parameter AH obtained is in good agreement with the calorimetric one and v is found to be independent of

## Abstract The helix–coil transition in poly(γ‐benzyl L‐glutamate‐__co__‐γ‐methyl L‐glutamate) copolypeptides was studied experimentally in nonaqueous solvents and the results compared with theory. It is found that the transition can be described by the same theory as for the homopolypeptides, but
