“…In view of the possible application of the CF, laser for UFe photochemistry and the scarcity of other highintensity 16-pm sources, this laser has received much attention in the recent past ( l-4). Part of this effort has been concentrated on the v2 + u4 absorption band which is used to pump the laser (5)(6)(7). To identify the many absorbing transitions, high-resolution diode laser spectroscopy measurements were carried out both at room temperature (5) and at 13 1 K (6).…”

Absorption and linewidth measurements of the R+(29) (v2 + IL,) A: + E9 + Fi4 transition in CF., are reported as a function of gas pressure and temperature. From these a value for the Einstein A coefficient (0.0185 f 0.0010 set-') is deduced. A model for low temperature absorption and a detailed analysis of additional absorption lines are given. The Doppler width reported by Eckhardt et al. (J. Mol. Spectrosc. 90, 321-326 (1981)) at 150 K is confirmed, while the homogeneous linewidth is found to be 10% smaller. The frequency displacement of the absorption feature from the CO2 9R(12) emission line center is found to be (34 + 2) MHz independent of temperature and pressure as may be expected. The room temperature absorption measurements of Radziemski et al.
