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.
