Abstract
“Infrared spectra for the series $CF_{3}CCX$ (where $X = H, D, F, Cl, $Br, and I) have been taken in the range 2.5-38 microns. Assignment of the fundamentals is made on the basis of band type, position and frequency relationships. The coupling of the $A_{1}$ fundamentals is traced as the C-X stretching frequency varies from $3325 cm^{-1}$ in $CH_{3}CCH$ to $770 cm^{-1}$ in $CF_{3}CCI$. The $CF_{3}$ asymetric stretching vibration is remarkably constant at $1170-1180 cm^{-1}$, and the $CF_{a}$ asymmetric deformation mode varies from 600 to $620 cm^{-1}$.”
