Abstract
We report here the results of our high pressure infrared absorption investigations on Bis(glycinium)oxalate, an organic complex of glycine. The observation of Raman active modes in the IR spectra beyond 1.6 GPa indicates the emergence of a non centrosymmetric high pressure phase. The pressure induced changes in the infrared active modes also indicate another structural transformation above 4.5 GPa. High pressure behavior of OH stretching mode of this compound has been studied to obtain the information about O–H⋯O hydrogen bond at higher pressures.
