  1. Water sorption ability of acetylated wood assessed by mid infrared spectroscopy Maria-Cristina Popescu, Carmen-Mihaela Popescu Petru Poni Institute of Macromolecular Chemistry of Romanian Academy, Iasi, Romania

  2. The purpose of this study was the Samples WPG % evaluation of the interactions that Reference 0 appear between water molecules and chemically modified wood 4 structure and the mechanism of adsorption of water by mid 8 infrared spectroscopy. Acetylated 13 17

  3. Pine wood samples of mm 3 dimension 20x20x5 (radial x tangential x longitudinal) were used for the experiments. The samples were kept at different RH values for 48h.

  4. FTIR spectroscopy 2 nd derivative spectra in 2 nd derivative spectra in 1690-1520 cm -1 region 3700-2750 cm -1 region
