Bott, J F

The author measured the emission spectrum of the ..nu../sub 3/ band of SF/sub 6/ at 1780 /sup 0/K in a shock tube. At this high temperature, the emission peaks at a frequency of 907 cm/sup -1/ (11.02 ..mu..); at room temperature, the band has a peak intensity at 948 cm/sup -1/. Lyman and Nowak observed similar but proportionately smaller shifts of the spectral maximum to lower frequencies at temperatures between 400 and 800 /sup 0/K. A knowledge of the high-temperature spectral distribution of the ..nu../sub 3/ band is important for the design and interpretation of isotope separation experiments in which SF/sub 6/ is dissociated by selective multiphoton absorption of CO/sub 2/ laser photons.
