## Abstract The far infrared spectra of poly(L‐proline) I (190–35 cm^−1^) and II (400–35 cm^−1^) were obtained in the solid state at both 300° and 110°K. A significant difference in the region below 100 cm^−1^ was observed. A very intense band located at 60 cm^−1^ in the infrared spectrum of form I
