Some observations on the capabilities of photoacoustic Fourier transform infrared spectroscopy (PAFTIR)

Abstract
The interfacing of a photoacoustic cell to a Fourier transform infrared spectrometer is described. The performance of the system with some powder and film samples has been evaluated and the differences between the photoacoustic spectra and corresponding transmission spectra are discussed. Data are presented that indicate the possibility of quantitative analysis employing the PAFTIR system.
