Abstract
The infra‐red absorption spectrum of gaseous 1,1,1‐trifluoroethane between 2 and 23μ has been investigated with a prism spectrometer of high resolution. The Raman spectrum of CF3–CH3 in the gaseous state has been photographed with a three‐prism glass spectrograph of linear dispersion 15A/mm at 4358A. The 12 fundamental frequencies have been assigned, and the spectra have been interpreted in detail. Thermodynamic functions have been calculated. A value of 3290 cal./mole has been obtained for the potential barrier opposing internal rotation.Keywords
