Linewidth measurements of the nu/sub 2/ + nu/sub 4/R/sup +/(29) A/sub 1//sup 4/ + E/sup 9/ + F/sub 1//sup 14/ absorption at 1073.279 cm/sup -1/ were made in the pressure range of 0.5 to 50 Torr CF/sub 4/. The data, after correction for Doppler broadening, reduce to a self-broadening coefficient of 10.8 +- 0.4 MHz/Torr. Comparisons of the linewidth for pure CF/sub 4/ with the linewidth of an Ar-CF/sub 4/ mixture and with the prediction of the hard-sphere, gas-kinetic model imply a relaxation mechanism that is not dominated by a resonant (V-V) process, and has an effective cross section that is intermediate in size between the cross sections associated with dipole-dipole and hard-sphere collisions.
