测定了8种木质纤维素副产物（小麦秸秆、大麦草、大豆豆荚壁和豆荚茎、苜蓿茎、玉米棒和玉米杆以及红橡叶）的傅里叶变换红外光谱。在吸收强度的相对差异，但不是最大值在木质素regions.Absorption的最大吸收，通过使用光谱的二阶导数，而吸收强度的差异最好的比较，通过使用一阶导数。
Fourier transform infrared spectra of eight lignocellulosic by-products (wheat and barley straws, soya bean pod walls and stems, alfalfa stems, corn cobs and stalks and red oak leaves) were obtained. Relative differences in absorption intensity but not maxima in the lignin region were found. Absorption maxima were obtained by use of second derivatives of the spectra, while differences in absorption intensities were best compared by use of first derivatives.
