TI - Vibrational Analysis of Poly(L-lactic acid) N2 - 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 UR - https://drive.google.com/file/d/1eVgtQEqmsO5hiXG5nAMHIQneqeNR7Qok/view?usp=drivesdk ER -
