✦ Synopsis

The specific heat a t low temperatures depends on long-range order of the solid because only the long-wavelength phonons are involved. We have recently shown that in biopolymers the secondary and tertiary structures can be studied by such an investigation.' To confirm the results found on L-alanine and a-and P-poly(L-alanine) [(Ala),], we have examined L-valine and poly(L-valine) [(Val)"], which presents a 6-pleated-sheet form in the solid state characterized by interchain hydrogen bonding.2
