    摘要： 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 λ, and b) determining the spectral measurement function I′(λ) with the aid of the absorbed, reflected, emitted and/or scattered radiation, wherein a correlation function K(δλ,c′,c) is determined according to Equation I K ⁡ ( δ ⁢   ⁢ λ , c ′ , c ) = 1 / N · ∫ - ∞ + ∞ ⁢ I ′ ⁡ ( λ , c ′ ) · I ⁡ ( λ + δ ⁢   ⁢ λ , c ) ⁢   ⁢ ⅆ λ ( I ) in which K(δλ,c′,c) denotes the correlation depending on the relative shift δλ of the functions I′(λ,c′) and I(λ,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′(λ,c′) denotes the measurement function of the at least one homogeneously distributed chemical compound V′ in a medium containing the concentration c′, I(λ,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(δλ,c′,c).
