Abstract

The presentation of absorption intensities in infrared spectra is usually limited to relative intensities, instead of absolute intensities. The measurement of absolute intensities would be facilitated by the existence of accepted secondary intensity standards that could be used to calibrate the path length of a transmission cell or the number of reflections in an attenuated total reflection cell. Under the auspices of the Molecular Spectroscopy Commission of the International Union of Pure and Applied Chemistry, we have developed proposals for such secondary standards based on the absolute intensities of benzene, chlorobenzene, and toluene.
