Abstract
Abstract The effect of hydrostatic pressure up to 4 GPa on the two polymorphs of glycine α — s.g. P21/n, and γ — s.g. P31 (P32)) was studied by X-ray powder diffraction using a synchrotron radiation source (λ = 0.7 Å, a MAR345 image plate detector). No polymorphic transformations were detected. Relative volume changes and the aniso tropy of structural distortion of the two polymorphs were compared. The directions of maximum and minimum lattice strain were related to the directions of weak and strong hydrogen bonds in the structures.
