Abstract
The GL (Air Force’s Geophysics Laboratory) high resolution Fourier transform spectrometer has been used to measure spectra of a $^{13}C$ enriched sample of $CO_{2}$ heated to 800K in a high temperature absorption cell. The single pass cell had an absorption path of 1.75 meter, where the central 1 meter section of the cell was maintained at 800K and a temperature gradient was present in the two end sections. The enriched sample consisted of 88\% $^{13}C^{16} O_{2},$ 11\% $^{13}C{^{1}6} O^{18}O,$ and 1\% various other isotopes. Results of the line position analysis will be presented at the Symposium. This work was supported by the Air Force Office of Scientific Research (AFOSR) as part of GL Task 2310G1.
