## Abstract Molecular motion in solid poly(Lβalanine), Poly(Lβleucine), poly(Lβvaline), and polyglycine has been investigated through measurement of the portion spinβlattice relaxation time at 30 and 60 MHz between 110 and 350Β°K. Rapid random reoriention of siedβchain methyl groups provides the dom

Solid state nmr methods were applied to the study of the motions and structural heterogeneity in polyglycine, sodium poly (L-glutamate) , and poly (L-alanine ) . The response of both the main-chain and side-chain resonances to the addition of water was studied using static and magic-angle sample-spi
Heat capacities of polyglycine, poly( L-alanine), and poly (L-valine) were analyzed using approximate group vibrations and fitting of the skeletal vibrations to a two-parameter ( 01, O3 ) Tarasov function. New experimental data were measured by differential scanning calorimetry in the temperature ra
The effect of progessive hydration up to 60% by weight of Hz0 and D20 on the proton relasation of polycrystalline achymotrypsin and lysozyme has been examined. The dynamical behaviour of the protein molecules was not affected by hydration. The dynamics of the water molecules was characterized. and t
