✦ Synopsis

In this brief note we extend our previous low-temperature specific heat measurements' on the simplest homopolypeptide polyglycine (Gly),, to the high-temperature range of 15@375 K using differential scanning calorimetry. Polyglycine, or poly(C0-CHR-NH) with R = H. is dimorphic in the solid state,' existing as a P-sheet structure [(Gly),tI] or as 3 , helices

## Abstract Detailed inelastic, incoherent neutron‐scattering (INS) spectra are presented for poly‐L‐alanine in both the α‐helical and β‐sheet form. Assignments are made from previous normal coordinate calculations. Of particular interest is the methyl torsion at 230 cm^−1^, which is the strongest

## Abstract This is one of a series of studies on the reversal of the helix sense of polyaspartates originated from the pioneering work of Goodman and his associates in 1960s. Poly(β‐p‐chlorobenzyl L‐aspartate) (PClBLA) is one of the well‐studied polyaspartate derivatives in both solution and the s
