Sterically allowed forms of the poly-N-methyl-calanine chain were found by calculation of conformational energies as a function of the rotation angles of its chain bonds. The lowest energy form seems to be a right-handed, approximately threefold helix.

## Abstract The normal vibration frequencies of poly(L‐alanine) and poly(L‐alanylglycine) in the antiparallel chain‐pleated sheet structure have been calculated, using the force field for polyglycine I from the previous paper (__Biopolymers__ **15**, 2439–2464) plus additional force constants for t
The chain conformation of poly-Lalanine in dichloroacetic acid has been investigated by combining experimental data on optical rotatory dispersions, intrinsic viscosities, and sedimentation equilibria. Comparison of experimentally obtained characteristic ratio with that predicted from theory leads t
