Polarized Raman Spectra and Infrared Analysis of Vibrational Modes in L-Threonine Crystals

Polarized Raman and infrared spectra of l-threonine crystals have been obtained at room temperature and an assignment of normal modes is proposed based on group theory analysis. The usefulness of these assignments comes from the fact that some modes are related to important vibrations that can show changes under different pressure and temperature conditions
