摘要
The effect of hydrostatic compression on the elastic and electronic properties of beta-glycine was studied using a quantum crystallography approach. The interrelations between the changes in the microscopic quantum pressure in the electronic continuum, macroscopic compressibility and piezoelectricity were considered. The geometries and energies of hydrogen bonds in the crystal structure of beta-glycine were considered as functions of pressure before and after a phase transition into the beta'-phase in relation to the mechanism of this phase transition.
