Bott, J F

The emission spectrum of the nu3 band of SF6 at 1780/sup 0/K is measured in a shock tube. At this high temperature, the emission peaks at a frequency of 907/cm (11.02 mu); at room temperature, the band has a peak intensity at 948/cm. 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 nu3 band is important for the design and interpretation of isotope separation experiments in which SF6 is dissociated by selective multiphoton absorption of CO/sub 2/ laser photons.
