Abstract

Changes in crystallinity of wood cellulose in situ under gamma radiation were investigated with infrared (FTIR) spectroscopy and X-ray diffraction technique. The correlation between degree of crystallinity determined by X-ray diffraction and crystallinity index calculated with normal and second-derivative IR spectra were studied. Good correlation obtained only for ratio A₁₃₇₃/A₂₈₈₅. It has been shown that absorbance/valley ratio: A_{1373 cm-1}/A_{1350 cm-1} or A_{1160 cm-1}/A_{1148 cm-1} with FTIR spectra can be used for estimation crystallinity of wood cellulose in situ.
