## Abstract The values of maximum frequencies, intensities, and other spectral parameters of the main absorption bands of amino acid residue sideβchain groups have been obtained in the 1500β1800βcm^β1^ region for solutions in heavy water at pD 1β12. It is shown that absorption of residues of aspara

Poly-irtyrosine absorbs strongly a t 1515 cm.-l, and a band a t this frequency has been found in a number of proteins and has been assigned to the tyrosine residue. The assignment was confirmed by examination of spectra of deuterated proteins, which nsrially exhibit a residual band a t 1513 an.-'.

Far-infrared spectra were measured for the sequential copolymers of amino acids with alkyl group side chains. The analysis of the spectra showed that (LAla-LAla-Gly),, (LAl\*Gly),, (LAla-Gly-Gly),, (LVal-L-Ala-L-Ala),, and (L-Val-LAla), have the antiparallel pleated sheet structures and that the bac
