Abstract The sampling methodologies employed in Fourier Transform Infrared (FT-IR) spectroscopy tend to distort to a degree the data obtained relative to that which would be obtained via transmittance. This distortion complicates data base searching. A standard sample of polystyrene was investigated using the techniques of transmittance, attenuated total reflectance (ATR), diffuse reflectance (DRIFT) and photoacoustic spectroscopy (PAS). Several types of corrections are employed to minimize the distortions due to sampling methodologies. These corrections are evaluated with respect to four distinct search algorithms. The results obtained indicate that proper mathematical treatment of the data prior to data base searching enhances the discrimination value of a data base search.
