Using a piezoelectric-translator-tuned cw CO/sub 2/ laser and a diode laser operating at 9 ..mu..m, many high-resolution spectra of the ..nu../sub 2/ + ..nu../sub 4/ band of /sup 12/CF/sub 4/ have been taken. Locations of absorption features within a few megahertz of several CO/sub 2/ lines used to pump a /sup 12/CF/sub 4/ 16-..mu..m laser have been identified. Absorption coefficients of /sup 12/CF/sub 4/ under cooled conditions have been measured within the CO/sub 2/ low-pressure gain lines. Detailed, consecutive diode-laser measurements across the P, Q, and R branches of the ..nu../sub 2/ + ..nu../sub 4/ band, taken at low temperature to eliminate hot bands, have led to tentative frequency assignments of the difficult spectrum of this molecule. Details of the frequency-assignment work will be presented in a later publication.
