The experimental setup for saturation absorption spectra research is described in detail. The spectrum of SiF4 molecule were observed in CO2-laser frequency range within P(30) rotational line of vibrational transition 9.4 µm. Saturation resonances with 400 kHz width and 50 Db signal-noise ratio were obtained. SiF4 spectral lines pressure broadening was measured: (11.0 ± 0.6) MHz/Torr.
