摘要：
For getting a better understanding of molecular association between water and wood, molecular structure of desorbed water in a typical wood (i.e. heat-treated wood) during moisture desorption process was investigated using micro-FTIR spectroscopy. Spectra were collected in the relative humidity (RH) region from high level to low level. A qualitative analysis of these spectra and corresponding difference spectra confirmed moisture sorption sites and determined main spectral region affected by moisture sorption. In addition, from component peak analysis of the identified spectral region of diffe...
