Notes: Poly(L-valine) (PLV) belongs to the class of polyamino acids having a bulky side chain. It preferably adopts the β-sheet conformation, although high molecular weight PLV may form an α-helix as well. In the present article we report a detailed study of the phonons and their dispersion for β-PLV and the spectra of oligovalines in relation to its polymeric form. The N-deuterated analogue of β-PLV has also been studied to check the correctness of assignments and force field. Density of states and heat capacity have been obtained. The heat capacity is in very good agreement with the experimental measurements of Roles et al. © 1996 John Wiley & Sons, Inc.
