Infrared spectra of polyglycines I and II obtained at −170°C. have been compared with those obtained at room temperature. The changes in frequency of some of the C—H stretching bands are consistent with the earlier suggestion that C—H … OC hydrogen bonds are present in the structure of polyglycine II.
