    Abstract: The present invention relates to a method for determining the identity or non-identity of at least one chemical compound V' homogeneous y 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(deltalambda,c',c) is determined according to Equation I K ⁡ ( delta ⁢ ⁢ lambda , c ' , c ) = 1 / N . ∫ - ∞ + ∞ ⁢ I ' ⁡ ( lambda , c ' ) . I ⁡ ( lambda + delta ⁢ ⁢ lambda , c ) ⁢ ⁢ ⅆ lambda ( I ) in which K(deltalambda,c',c) denotes the correlation depending on the relative shift deltalambda 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, c' 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(deltalambda,c',c).
