Novel Spectrophotometric Protocol for the Long-Term Characterization of the Hue of Artwork

Langhals, Heinz ; Schlücker, Thorben and Ernst, Helena (2017): Novel Spectrophotometric Protocol for the Long-Term Characterization of the Hue of Artwork. In: Analytical Letters, Vol. 50, No. 14: pp. 2270-2278

Abstract

A method for the highly precise, long-term documentation of the color of artwork is described. Gaussian analysis of several ultraviolet-visible absorption spectra allowed the generation of a reduced data set of three to seven Gaussian bands. High-resolution absorption spectra were characterized as 21 or fewer numerical data. The spectral approach enables chemical identification independent from the illumination and concentration of the sample. Applications including documentation and authentication are discussed.
