Normal vibrations of crystalline polyglycine I
(Wiley Subscription Services, Inc., A Wiley Company, 1972-09)
A valence force field has been refined for crystalline polyglycine I using its known antiparallel chain pleated-sheet structure and without replacing the CH 2 group by a point mass. Polyglycine I and four of its isotopic ...
Normal vibrations of polyglycine II
(Wiley Subscription Services, Inc., A Wiley Company, 1972-09)
A valence force field has been refined for single-chain polyglycine II using the known structure and four isotopic derivatives. The calculated frequencies are in good agreement with the observed. The force field is compared ...
