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

摘要

The infrared spectra of gaseous CF3CH2Cl and CF3CHCl2have been obtained in the range from 2 to 38mgr;, and the spectra of the liquids in the range from 2 to 22mgr;, with the aid of LiF, NaCl, KBr, and KRSminus;5 prisms. The Raman spectra of these compounds in the liquid state have been photographed with a threehyphen;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.
