    Abstract: Disclosed is a method for determining the identity or non-identity of at least one chemical compound V' homogeneously distributed in a medium, by a) exposing the medium containing at least one homogeneously distributed chemical compound V' to analysis radiation with a variable wavelength (lambda), and b) determining the spectral measurement function I'(lambda) with the aid of the absorbed, reflected, emitted and/or scattered radiation, wherein a correlation function K(delta lambda,c',c) is determined according to Equation (I), in which K(delta lambda,c',c) denotes the correlation depending on the relative shift (delta lambda) of the functions I'(lambda,c') and I(lambda,c) and the concentrations c' and c of the at least one chemical compound V' and V, cÆ denotes the concentration of the at least one chemical compound V' homogeneously distributed in the medium, with a known or suspected identity, c denotes the concentration of the at least one chemical compound V homogeneously distributed in the medium, with a known identity, I'(lambda,c') denotes the measurement function of the at least one homogeneously distributed chemical compound V' in a medium containing the concentration c', I(lambda,c) denotes the comparison function of the at least one homogeneously distributed chemical compound V in a medium containing the concentration c, and N denotes a normalization factor, and identity or non-identity between the compounds V' and V is determined with the aid of the correlation function K(delta lambda,c',c), and the identity or non-identity of at least one chemical compound V' homogeneously distributed in a liquid or solid medium is determined. Also disclosed is the use of the above method wherein the at least one compound V and the at least one compound V' are tagging substances for mineral oils.
