Abstract:
Beech wood (Fagus sylvatica L.) veneers were cultivated with white and brown rot fungi for up to 10 weeks. Fungal wood modification was traced with Fourier transform near infrared (FT-NIR) and Fourier transform mid infrared (FT-MIR) methods. Partial least square regression (PLSR) models to predict the total lignin content before and after fungal decay in the range between 17.0% and 26.6% were developed for FT-MIR transmission spectra as well as for FT-NIR reflectance spectra. Weight loss of the decayed samples between 0% and 38.2% could be estimated from the wood surface using individual PLSR models for white rot and brown rot fungi, and from a model including samples subjected to both degradation types.

IR and UV–Vis Spectroscopy of Carboxylic Acids
However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency, 1710 cm−1. The C=O bond of the...
