## Abstract The difference in the observed frequency of the amide I mode between the Raman and ir spectra of many unordered polypeptides is interpreted in terms of a model in which sequences of amide groups have similar ϕ, ψ angles. The splittings due to intramolecular interactions for the infinite
## Abstract Ultraviolet resonance Raman (UVRR) spectra of polypeptides and proteins exhibit a band at __ca.__ 1390 cm^−1^ whose intensity is sensitive to helical content. The assignment of this band, designated amide S, has been contentious. To study the vibrational origin of amide S, relevant amid
