Raman scattering and synchrotron X-ray diffraction have been used to
investigate the high-pressure behavior of L-alanine. This study has
confirmed a structural phase transition observed by Raman scattering at
2.3 GPa and identified it as a change from orthorhombic to tetragonal
structure. Another phase transformation from tetragonal to monoclinic
structure has been observed at about 9 GPa. From the equation of state,
the zero-pressure bulk modulus and its pressure derivative have been
determined as (31.5 +/- 1.4) GPa and 4.4 +/- 0.4, respectively. (C) 2008
