The Use of FTIR and Micro-FTIR Spectroscopy: An Example of Application to Cultural Heritage [PDF]

open access: yesInternational Journal of Spectroscopy, 2009
Micro-FTIR and FTIR spectroscopy is useful for the study of degradation forms of cultural heritage. In particular it permits to identify the degradation phases and to establish the structural relationship between them and the substratum. In this paper, we report the results obtained on marble from a Roman sarcophagus, located in the medieval cloister ...
