TL;DR: In this article, the exact absorption intensities of the three infrared active fundamental vibrations of each of the cyanogen halides (CICN, BrCN, and ICN) have been measured for crystalline samples, using experimental techniques developed by Hollenberg and Dows.
Abstract: Absolute absorption intensities of the three infrared‐active fundamental vibrations of each of the cyanogen halides—CICN, BrCN, and ICN—have been measured for crystalline samples, using experimental techniques developed by Hollenberg and Dows Comparison between integrated intensities obtained with “drawn in” backgrounds and those obtained after integrating the absorption coefficient, κ, obtained from the measured transmittance by a Kramers–Kronig method, shows that the results agree within their estimated experimental uncertainty The intensities of the stretching fundamentals in the solid phase differ drastically from those in the gas phase, eg, ν1 for ClCN goes from an estimated 900 darks in the gas phase to 0 in the solid, ν3 increases by a factor of 2 from gas to solid for ClCN, and by a factor of about 4 for BrCN However, the solid phase intensities of ν2, the bending motion perpendicular to the molecular chains in the solid, are only slightly larger than the gas phase values, indicating that the
