Abstract
A high resolution step-and-hold Fourier transform spectrometer has been used to observe the spectrum of CO2 samples heated to 800 K in a high temperature absorption cell. The interferograms were recorded using a maximum optical path difference of 152 cm resulting in an apodized spectral resolution of 0.007 cm-1. The 20 torr isotopically enriched CO2 sample consisted of 88% 13C16O2 and 11% 16O13C18O. The sample was contained in a single pass high temperature absorption cell with a total absorption path length of 1.75 meters. A total of 1601 lines belonging to 15 rotation-vibration bands of 13C16O2 and 146 lines belonging to two bands of 16O13C18O were identified in the observed spectrum. A weighted least-squares fit was then used to obtain improved estimates of the band centers and rotational constants.
