The Raman and IR spectra of poly(L-lactic acid)in the amorphous and semicrystalline states were recorded from 3600 to 100 cm-'. Complete vibrational assignments are proposed. In the Raman spectra, the splittings of the vC=O stretching and the SCCO bend are characteristic of the crystalline phase and the presence of the two ines at 923 and 520 cm- ' indicates a 10, helical conformation.
