A definitive analytical spectroscopic study of Indian yellow, an ancient pigment used for dating purposes

A major factor in the deployment of analytical Raman and infrared spectroscopy for the characterization of pigments in works of art is the existence of a database in the literature which facilitates the comparison of spectral signals with those of standards for the recognition of the spectra recorded from single pigments and from components in admixture. The interpretation of these spectral data and their assignment to particular molecular species enables the presence or otherwise of a pigment to be determined in the specimens which itself can be used to identify materials which may be out-of-context chronologically in disputed artworks.
