Infrared and Raman Spectra of Fluorinated Ethanes. XII. 1,1,2,2-Tetrafluoroethane

The infrared absorption spectra of gaseous CHF2–CHF2 at five temperatures between 30° and 170°C and of the crystalline solid at —170°C have been obtained with a Perkin-Elmer double-pass spectrometer equipped with CsBr, NaCl, and LiF prisms. The Raman spectrum of the liquid at 20°, —25°, and —80°C ha...
