| Popis: | Infrared and Raman spectra of DL-threoninium dihydrogenphosphate crystal were recorded at room temperature and vibrational assignments of the observed wavenumbers were made. The extensive intermolecular hydrogen bonding in the crystal was identified by the shifting of bands due to the stretching and bending modes of the various functional groups. The Td symmetry of the phosphate anion is reduced to the lower symmetry C2v owing to the intermolecular hydrogen bonding and coordination. The splitting of degenerate modes and the appearance of infrared-inactive modes indicate the effect of the crystalline field on molecular vibrations. Copyright © 2004 John Wiley & Sons, Ltd. |
