Infrared and Raman Spectra of Fluorinated Ethanes. VIII. Pentafluoroethane

Abstract

The infrared spectrum of gaseous CF₃CF₂H has been observed in the region from 2 to 38μ, and the spectrum of the liquid at — 50°C from 2 to 22μ, with the aid of LiF, NaCl, KBr, and KRS‐5 prisms. The Raman spectrum of gaseous CF₃CF₂H has been photographed with a three‐prism glass spectrograph of linear dispersion 15 A/mm at 4358 A. All but one of the fundamental vibration frequencies have been assigned, and the spectra have been interpreted in detail.
