  • Title: Vibrational spectral studies of L-citrullinium perchlorate.
    Author: Ali Jinnah MM, Sasirekha V, Ramakrishnan V.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2005 Dec; 62(4-5):840-4. PubMed ID: 15953761.
    Abstract:
    Infrared and Raman spectra of L-citrullinium perchlorate crystals have been recorded at room temperature. The vibrational assignments of the observed wavenumbers are proposed on the basis of group theoretical analysis. The presence of carbonyl group indicates that the molecule exists in the ionic form. The shifting of stretching and bending wavenumbers indicates the presence of extensive hydrogen bonding in the crystal. The anion fundamentals however continue to be degenerated. This suggests that its symmetry is not affected in the crystal.
