Raman investigation of Middle Eastern Manuscripts

The Middle Eastern Manuscript Collection, collected by Professor John Bowman at the University of Melbourne, is an important collection but requires substantial research before conservation treatment can be undertaken. Raman spectroscopy is a particularly useful tool for manuscript investigation, providing “through air” analysis of works of art giving a high degree of analytical results without the need to take samples. This makes Raman analysis particularly relevant for works of art from which sampling is difficult, such as extremely rare works, those in extremely good condition or small works. Raman also provides the ability to analyse the structure of both organic and inorganic compounds. Raman can focus on very small particles, and pigment grains within a matrix can be selectively analysed. Raman also provides information related directly to the sample through the capacity to visually reference the area being analysed during the analytical process, making it useful in quick and readily referencing analytical results. A substantial reference data base has been established and a number of important manuscripts have been analysed. A symposium The Care and Conservation of Middle Eastern Manuscripts was hosted by CCMC in December 2007.
