FT-Raman spectroscopy is used for the rapid measurement of wood pulp lignin. A total of 23 western softwood pulp samples with known kappa numbers (10 -38) are used. Each sample is divided into three portions and scanned separately. The integrated area of the lignin band at approximately 1600 cm 01 i

Wool fibers are comprised of proteins known as a-keratins and have a complex morphological structure. The major components of this structure, the cuticle and cortical cells, differ in the conformations of their peptide chains as well as their amino acid compositions. High quality Fourier transform R
## Abstract It is demonstrated that the use of pulsed lasers in nearβinfrared Fourier transform Raman spectroscopy can give a significant increase in signalβtoβnoise ratios over continuousβwave measurements made using the same average laser power. It is also shown that when a thermal (or other rela
