title: [The identification of mineral oil pollutions by the combination of IR-and fluorescence spectroscopy (author's transl)].
abstract: By evaluation of the quotient Q = intensity of fluorescence: intensity of C-H-vibration a relative number  has been obtained, which, independend of concentration and largely substance specific, enables to make more exact statements on identifying oil spills than those derived only from IR-spectroscopic measurement. The Q-values of 33 different mineral oil products have been calculated and are compared with the intensity ratio V of the asymetric CH2- and CH2-stretching bands and the absorbtivity of these bands, which commonly are used. Q, exhibiting values from 0,0015 to greater than 5000 has proved to be a very sensitive number while the maximum ratio of the V resp. absorptivity values was only 1:13. The scope of Q is discussed on the basic of three examples.
