Infrared spectroscopy and microspectroscopy are versatile sampling methods allowing one to perform a variety of experiments including transmission, absorption-reflection, specular reflection, attenuated total reflection (ATR) and diffuse reflection experiments.
Our research group has used infrared spectroscopy to develop several analytical methods: the characterization of historic papers using ATR, the quantitation of asbestos in airborne and bulk samples using diffuse reflection, the identification of microscopic paint fragments from medieval manuscripts using transmission microspectroscopy, and the classification of bacterial colonies in-situ using specular reflection and ATR microspectroscopy. Our recent work involves identifying the pigments and other materials (binders, additives, fibers) on a medieval polychrome wooden sculpture housed in the David Owsley Museum of Art. Additionally, our group is collaborating with metal chemists at Element-Daleville to develop an improvised method for analysis of metal oxides.
