Raman spectra and the phonon dispersion of polyglycine

The Raman spectra of the two crystalline modifications of polyglycine, I and II, and of N-deuterated polyglycine II have been recorded. The results of a normal-coordinate analysis of polyglycine II and N-deuterated polyglycine II are presented along with the phonon dispersion curves of polyglycine I...

Zusammenfassung:	The Raman spectra of the two crystalline modifications of polyglycine, I and II, and of N-deuterated polyglycine II have been recorded. The results of a normal-coordinate analysis of polyglycine II and N-deuterated polyglycine II are presented along with the phonon dispersion curves of polyglycine II. Assignments are made on a number of bands not observed in the infrared. Some previous band assignments are found to be inconsistent with the Raman data.
