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.
