Abstract
High-pressure behaviour of α-glycine has been investigated up to ~23 GPa using Raman scattering technique. The experimental results show slope change in the CO2 bending, NH3 torsional and NH3 rocking modes around 3 GPa and are interpreted in terms of change in the nature of an N-H···O-C intra-layer hydrogen bond at this pressure. Several other spectral features seem to arise from pressure-induced variations in the inter-molecular coupling.
