Studies of the 3..nu../sub 3/ absorption band in SF/sub 6/ in the spectral region from 2800 to 2850 cm/sup -1/ have been completed with a FT--IR spectrometer at a spectral resolution of 0.04 cm/sup -1/. This study confirms the results reported earlier by Kildal on the general shape of this absorption band. The absorption has been studied as a function of temperature, allowing a definite assignment to be made of the ground state features observed in this spectrum at room temperature. The ground state absorption to 3..nu../sub 3/ appears with a double Q branch (estimated band origins at 2830.22 and 2827.62 ( +- 0.06) cm/sup -1/). The intensities and temperature dependence studies confirm the assignment by Fox of these two Q branches to the two F/sub 1u/ components of the 3..nu../sub 3/ state.
