The spectra of the 1, 211, 2, 22, and 322 bands of CF4 were obtained with a quasi-continuous wave stimulated Raman spectrometer. These five bands were studied at a temperature of 135 and 300K (for the hot bands). The spectrum of 1 was obtained at a sample pressure of 2mbar. For the spectra of the other regions, which are much weaker, higher pressures were used. The analysis has been performed thanks to the xtds and spview softwares developed in Dijon for such highly symmetric molecules. Combining the present results with a previous infrared study, we could determine a very accurate value for the CF equilibrium bond length, i.e. re=1.31588(6)angstrom.
