Abstract
The infrared absorption spectrum of gaseous CF 2BrCCl 2Br at room temperatures has been obtained in the region 300–3500 cm −1 with a Perkin-Elmer double-pass spectrometer equipped with CsBr, NaCl, and LiF prisms. In addition, the infrared spectrum of the solid was recorded at 30° and −170°C, and certain spectral regions were studied with the sample dissolved in polar and nonpolar solvents. The Raman spectrum of the liquid at 55°C was photographed with a 3-prism glass spectrograph. The compound exists as a mixture of rotational isomers in all three states of aggregation. An attempt has been made to assign fundamentals, but sufficient data could not be obtained to differentiate between the fundamentals of the two rotational isomers.
