Abstract
Four of the strongest bands in Halocarbon F-12, $CCl_{2}F_{2}$ and three of the strongest bands in Halocarbon F-11, $CCl_{3}F$, have been measured with a moderate resolution $(0.06 cm^{-1})$ Fourier transform spectrometer. Care was taken to make sure that the Halocarbons were not being absorbed in the cell or in the transfer manifold by removing all elastomers. The samples were pressure broadened with nitrogen to one atmosphere. Most of the bands are in general agreement with other published results except $\nu_{4}$ of halocarbon F-11 at $846 cm^{-1}$. The present work indicates that the intensity of this band is $1828 \pm 12 cm^{-2} atm^{-1}$ about 15% higher than $Varanasi and Ko^{1}$ and 6% higher than $Goldman et al^{2}$.
