For lignocellulosic materials, water adsorption is extremely important for its product performance. For gaining a deeper understanding of moisture adsorption mechanisms, the molecular interactions between adsorbed water and a typical lignocellulosic material (i.e., wood) were studied using in-situ microscopic Fourier transform infrared (micro-FTIR) spectroscopy and a specially designed sample cell. The spectral shifts of 1733 cm(-1), 1604cm(-1) and 1236 cm(-1) and different spectra between the moist and dry spectra indicated that carbonyl C=O and C-O groups preferred to combine with water mole...
