Abstract

Polarized Raman spectra of L-asparagine were measured as a function of temperature. Various qualitative changes were observed. We believe that these changes are produced by hydrogen bond alterations and a second order phase transition around 160 K. We also observed anharmonicity in bands linked to the hydrogens bonds.
