## Abstract The normal modes have been calculated for structures having the dihedral angles of the four β‐turns of insulin. Frequencies are predicted in the amide I region near 1652 and 1680 cm^−1^. The former overlaps the α‐helix band at 1658 cm^−1^ in the Raman spectrum, while the latter accounts
