Abstract

Photoacoustic spectra of materials obtained using the Fourier transform technique require normalization to achieve correct relative peak heights over the spectral range studied. This paper discusses procedures for obtaining quantitative Fourier transform IR-photoacoustic spectroscopy spectra of solids and liquids. A normalization routine for absorption amplitudes is discussed and applied to experimental data obtained on polymeric samples.
