Raman spectroscopic library of medieval pigments collected with five different wavelengths for investigation of illuminated manuscripts (2018)
Journal Article
Marucci, G., Beeby, A., Parker, A., & Nicholson, C. (2018). Raman spectroscopic library of medieval pigments collected with five different wavelengths for investigation of illuminated manuscripts. Analytical Methods, 10(10), 1219-1236. https://doi.org/10.1039/c8ay00016f

Raman spectroscopy is widely applied in the cultural heritage field to perform non-destructive measurements in situ, in order to identify materials, specifically pigments. The spectra collected can be challenging to interpret because certain source l...
