โœฆ Synopsis

Raman and ir spectra of the glycyl-L-proline (GP) dipeptide were recorded. A normalcoordinate treatment was performed on the basis of the experimental spectra, using a modified Urey-Bradley force field (MUBFF). Cyclic redundancies were eliminated, and those due to the ring methylene groups, particularly distorted in regard to the tetrahedral conformation, were treated. An assignment of the experimental frequencies is proposed on the basis of the normal treatment.

We studied the Raman spectra of the zwitterionic glycylglycine crystal (GG) and its Ndeuterated analog. A normal coordinate analysis on its a-crystalline form was performed and the effects of intra-and intermolecular couplings are discussed. A modified Urey-Bradley potential was used as a model of t

## Abstract Using Wilson's GFโ€matrix method as modified by Higgs for infinite helical polymers, dispersion curves and the frequency distribution function have been calculated for polyโ€Lโ€proline II chain. Infrared spectrum is obtained and a Ureyโ€Bradley force field, which provides best fit with the
