High-pressure X-ray diffraction of L-ALANINE crystal

摘要

L-ALANINE has been studied by X-ray diffraction at ambient temperature and pressure up to 10.3 GPa. The material is found to transform to a tetragonal structure between 2 and 3 GPa and to a monoclinic structure between 8 and 10 GPa. The experimental bulk modulus is 25(5) GPa for the orthorhombic phase. The results are compared with previous measurements of L-ALANINE.
