In the first paper heat capacities C(p), of polyglycine, poly (L-alani
ne), and poly (L-valine) were analyzed using approximate group vibrati
ons and fitting the C(p) contributions of the skeletal vibrations to a
two-parameter Tarasov function. In this second paper all other poly (
amino acid) s are similarly analyzed. Heat capacities were measured by
differential scanning calorimetry in the temperature range of 230-390
K for Poly (L-leucine), poly (L-serine), poly (sodium-L-aspartate), p
oly (sodium-L-glutamate), poly (L-asparagine), poly (L-phenylalanine),
poly(L-tyrosine), poly(L-methionine), poly(L-tryptophane), poly(L-pro
line),poly(L-lysine.HBr), poly(L-histidine), poly(L-histidine-HCl), an
d poly(L-arginine.HCl). Good agreement exists between experiment and c
alculation. Predictions of heat capacities were made for all not-measu
red poly (amino acid) s. Enthalpies, entropies, and Gibbs functions fo
r the solid state have been derived.
