Far-infrared Bands of Amino-acid Residues with α-Helical and β-Form Conformations

Nature New Biology volume 239, pages 42–43 (1972)Cite this article

Abstract

INFRARED spectra in the far-infrared region are very sensitive to the conformational changes of polypeptide backbones1–6. We have measured the infrared spectra of sequential polypeptides in the region from 700 to 200 cm−1 and have found several far-infrared bands characteristic of component amino-acid residues with α-helical and β-form conformations.
