Identification of Archaeological Wood Species by IR Spectroscopy

We present the results of testing of the previously proposed method for identifying species of archaeological wood materials by single-reflection attenuated total reflectance IR spectroscopy. The region 1270–1220 cm–1, in which two bands of different intensities were found, is most promising for identifying the species of archaeological wood samples. In the spectra of coniferous wood, a more intense band is located at approximately 1265 cm–1, and in the spectra of deciduous species, a more intense band is at 1230 cm–1.
