Contributions of ¿NH3+ torsions to phase transitions of glycine

DOI

It is proposed to investigate the torsional dynamics of the ¿NH3+ group of glycine-d2 in its three polymorphic forms using quasielastic neutron scattering (QENS). This study is motivated by the fact that the three polymorphic forms of glycine have the same internal geometry and differ primarily in the details of hydrogen bonding between ¿NH3+ and neighboring ¿COO- groups. Differences are seen in the INS spectra that are likely due to anharmonic motion of the ¿NH3+ group. Glycine is one of the most extensively studied polymorphic systems.
