Applications of infrared photo-acoustic spectroscopy for wood samples

Informally Refereed

Abstract

Various infrared (IR) spectroscopic techniques for the analysis of wood samples are briefly discussed. Theories and instrumentation of the newly developed photoacoustic spectroscopic (PAS) technique for measuring absorbance spectra of solids are presented. Some important applications of the PAS technique in wood science research are discussed. The application of the Fourier transform infrared-photoacoustic spectroscopic(FTIR-PAS) technique is demonstrated by three preliminary studies of different forms of wood samples.
