The Raman spectra of poly-γ-benzyl-L-glutamate, poly-L-leucine, poly-L-valine, and poly-L-serine are reported. For the α-helical polymers, the conformationally sensitive amide I, II, and III modes are observed in the Raman as, well as the infrared. For the β form, the Raman effect, supplies the infrared inactive inphase motion which is useful for the determination of a parallel or antiparallel chain alignment. Modes characteristic of the specific polypeptide are also observed which are insensitive to conformation.
