Abstract
Polarised Raman, IR and FIR spectra of the monoglycine dihydrogenphosphate (glycinium dihydrogenphosphate) single crystal samples are presented and discussed with respect to the crystal structure on the basis of oriented gas model approximation. The IR and FIR spectra were measured by specular reflection method and spectra of an imaginary part of the refractive indices were computed by the Kramers-Kronig transformation. The polarisation properties of the internal vibrations of the glycinium cation, H 2PO 4 1− anion and hydrogen bonds are predicted and compared to the experimentally determined.
