Pressure up to 10 GPa is a powerful method for studying polymorphism in organic crystal
structures, and this review surveys work carried out on high-pressure polymorphism in …

The effect of high pressure on the crystal structures of α-, β-, and γ-glycine has been
investigated. A new polymorph, δ-glycine, is obtained from β glycine. δ-Glycine is …

High-pressure behaviour of α-glycine has been investigated up to∼ 23GPa using Raman
scattering technique. The experimental results show slope change in the CO2 bending, NH3 …

In this chapter, we investigate the Raman spectra of proteinogenic amino acid crystals.
Amino acids are fundamental organic molecules that compose polypeptides (a linear chain …

Single crystals of β-glycine were studied at pressures up to 7.6 GPa in a diamond anvil cell
(DAC) in situ by Raman spectroscopy and polarized optical microscopy. A reversible phase …

Use of the non-local correlation functional vdW-DF (from'van der Waals density functional';
Dion M et al 2004 Phys. Rev. Lett. 92 246401) has become a popular approach for including …

The results of a high-resolution powder diffraction study of the effect of high hydrostatic
pressure up to 8 GPa on the pure γ-polymorph of glycine (P 31) are discussed. A phase …

A Raman spectroscopy study has proven, that on increasing hydrostatic pressure up to∼
3GPa γ-glycine undergoes a phase transition into δ-polymorph, which on decompression …

The effect of pressure on l-alanine has been studied by X-ray powder diffraction (up to 12.3
GPa), single-crystal X-ray diffraction, Raman spectroscopy and optical microscopy (up to∼ 6 …

The series of phase transitions on increasing pressure and on reverse decompression was
followed in crystals of monoclinic and orthorhombic polymorphs of L-cysteine by using …
