Paper Abstract

Fourier self-deconvolution of a photoacoustic FTIR spectrum by direct manipulation of the observed interferogram is shown to be possible. Over a narrow frequency range, the measured photoacoustic (PA) signal is approximately proportional to the optical absorption coefficient, thereby enabling known line shapes to be used in the deconvolution. The method is applied to the PA spectrum of kaolinite and the enhanced spectrum is compared with other theoretical and experimental results.
