Infrared and Raman Spectra of Fluorinated Ethanes. VI. The Series CF3CH3, CF3CH2Cl, CF3CHCl2, and CF3CCl3

Abstract

The infrared spectra of gaseous CF₃CH₂Cl and CF₃CHCl₂ have been obtained in the range from 2 to 38μ, and the spectra of the liquids in the range from 2 to 22μ, with the aid of LiF, NaCl, KBr, and KRS−5 prisms. The Raman spectra of these compounds in the liquid state have been photographed with a three‐prism glass spectrograph of linear dispersion 15A/mm at 4358A. Depolarization ratios were determined for most of the Raman bands. All fundamental vibrational frequencies have been assigned; the spectra have been interpreted in detail, and thermodynamic functions have been calculated.
