- Abstract
- Resonance Raman spectroscopy has been utilized to identify vegetal and
animal dyes and lakes. These compounds have been used by artists since
antiquity, and their identification has important implications in art
history and conservation. The resonance condition is useful when
working with real ancient objects so as to enhance the Raman scattering
of chromophores with respect to the strong signal of the matrix, such
as the textile or parchment over which the colorant is supported. The
strong fluorescence that generally characterizes the resonance Raman
spectra was eliminated by using subtracted shifted Raman spectroscopy
(SSRS). A systematic study on reference organic dyes was primarily
carried out to evaluate the suitability of the method and to estimate
the strengths and limitations of the spectrum reconstruction process.
The method was then applied to the noninvasive identification of madder
on ancient dyed silk textiles such as an altar table cloth and a
manutergium attributed to the Egyptian artistic textile production of
the 10th-11th Century A.D. (literal)
