The lignin oxidation from sugarcane straw and bagasse using Fourier-transformed Infrared spectroscopy (FTIR) followed by principal component analysis (PCA) was also studied. 

Since the early 1950s, 1R spectroscopy has been a routine analytical tool for lignin chemists. In the past, spectra were recorded using the so-called dispersive technique, i.e., with grating-type or prism instruments. In the last decade, Fourier transform infrared (FT1R) spectrometers have become increasingly available for routine laboratory work.

Characterization of Lignin. Lignin is characterized in the solid state by Fourier transform infrared (ftir) spectroscopy, uv microscopy, interference microscopy, cross polarization/magic angle spinning nuclear magnetic resonance (cp/mas nmr) spectroscopy, photoacoustic spectroscopy, Raman spectroscopy. 

Kolboe and Ellefsen (1962) and Michell et al. (1965) provided preliminary results indicating the feasibility of employing infrared spectroscopy to determine the lignin content of finely ground wood and pulp samples embedded in potassium chloride. Further development and refinement of this technique have led to methods for determination of lignin based on multiple internal reflectance infrared spectrometry (Marton and Sparks 1967) and diffuse reflectance Fourier transform spectrometry (Schultz et al. 1985). Lignin contents have also estimated by 13C CP/MAS/NMR spectrometry (Haw et al. 1984, Hemmingson and Newman 1985) (see Chap. 4.5).
