Raman optical activity study of poly-L-proline chains of various lengths

Abstract

Raman and Raman optical activity (ROA) spectra of several oligo-and poly-L-proline samples of various chain lengths were measured in a wide frequency range between 120 and 1800 cm(-1) and analysed with respect to the main peptide chain conformation.
