Polarized ir and Raman spectra have been obtained on oriented films of a-helical poly(L-alanine) (a-PLA) and its N-deuterated derivative. These improved spectra permit a more complete assignment of observed bands to A-, E 1 -, and E 2 -species modes. A new empirical force field has been refined, bas
A normal coordinate analysis for cyclic tetra-Lalanine molecule is reported. A comparison of amide modes and other low-frequency vibrations sensitive to conformational changes is made with t.hose in poly-Lalanine. Intramolecular coupling coefficients are calculated using perturbation treatment.
