Abstract

By the method of saturation of absorption of counterpropagating light waves, the gas-phase spectrum of SiF4 is obtained without Doppler broadening of spectral lines. In the frequency range of the generation of a low-pressure CO2 laser (the 9.4-μm band), multiplets of the superfine structure (associated with tunneling transitions between the states of rotation about the equivalent symmetry axes of the SiF4 molecule) of the spectrum were observed. Weak satellites were observed in the vicinity of the multiplets. Some of the satellites were interpreted as resonances formed by the collisional transfer of the three-photon Bennett holes and peaks.
