abstract = {The hygroscopicity and thermodynamic properties of Pinus sylvestris L. wood from a coffin
allegedly holding the remains of famous Spanish author Miguel de Cervantes Saavedra (1547–1616)
were studied using the 15 ◦C and 35 ◦C isotherms fitted to the Guggenheim–Anderson–de Boer model
and comparing them with the isotherms of recently felled wood of the same species. In addition, using
infrared spectroscopy (FTIR-ATR) and X-ray diffractograms, the functional groups were determined
and the crystallinity and organization of the cell wall components were analyzed. The absence of
the 1740 cm−1 group indicates hemicellulose degradation in the archaeological wood, and the X-ray
diffractograms show a considerable decrease in cellulose crystallinity and disorganization of the
cellulose crystallites. The greater availability of active –OH groups means that the archaeological
wood isotherms are above the juvenile and mature wood isotherms, and therefore the thermodynamic
balance in the sorption of the archaeological wood is greater.},
