Elimination of dispersion-induced distortion in infrared absorption spectra by use of photoacoustic spectroscopy

Abstract

Fourier transform infrared photoacoustic techniques have been employed to remove the spectral distortion present in the transmission and reflectance spectra of powdered solids suspended in mulls and pressed pellets. Results are presented for AgCN. The photoacoustic data is also compared to that obtained by Raman spectroscopy.
