  • Title: Raman spectra of dipicolinic acid in crystalline and liquid environments.
    Author: Kolomenskii AA, Schuessler HA.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2005 Feb; 61(4):647-51. PubMed ID: 15649796.
    Abstract:
    Raman spectra of dipicolinic acid (DPA) are important for detection of bacterial spores, since DPA and its salts present one of their major components. The implementation of a deeply cooled CCD camera in combination with pulsed excitation at 532 nm allowed measuring well-resolved Raman spectra of the DPA in different forms. Powder preparations, crystals grown from saturated solutions and aqueous solutions of the DPA were studied. The spectral features in different environments and comparison with the spectra obtained by other methods are discussed.
