RAMAN-SPECTROSCOPIC LIBRARY OF NATURAL AND SYNTHETIC PIGMENTS (PRE-SIMILAR-TO 1850 AD)

To assist in the greatly increasing number of applications of Raman mi croscopy as a tool for non-intrusive, in situ archaeometric analysis, the Raman spectra of over 60 pigments, both natural and synthetic, kno wn to have been in use before similar to 1850 AD, have been studied by Raman microscopy. Fifty-six pigments have yielded high quality spectr a which have been arranged, by colour, into a spectroscopic library fo r reference purposes. The spectroscopic files may be downloaded from / /www.ucl.ac.uk/chem/resources/raman/speclib.html. (C) 1997 Elsevier Sc ience B.V.
