摘要：

The Raman and IR spectra of poly(L-lactic acid) in the amorphous and semicrystalline states were recorded from 3600 to 100 cm(-1). Complete vibrational assignments are proposed. In the Raman spectra, the splittings of the nu C=O stretching and the delta CCO bend are characteristic of the crystalline phase and the presence of the two lines at 923 and 520 cm(-1) indicates a 10(3) helical conformation.
