Application of FTIR spectroscopy to the characterization of archeological wood

open access: yesSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2016
Two archeological wood samples were studied by attenuated total reflectance Fourier transform infrared (FTIR-ATR) spectroscopy. They originate from a shipwreck in Ribadeo Bay in the northwest of Spain and from a beam wood of an old nave of the Cathedral of Segovia in the central Spain.
