Abstract:Nearly 1000 line intensities of $^{16}$O$^{12}$C$^{17}$O between 4604 and 5126 \wn were measured using an isotopically-enriched mixture sample having 40 \% (determined by mass spectrometry). Spectra were recorded at 0.0056 \wn resolution with a Fourier transform spectrometer (Bruker IFS-125HR at JPL) configured to a Herriott cell with a 20.946 m absorption path. Since collisional narrowing effects were observed, the Rautian profile was systematically applied (instead of the Voigt profile) using a multispectrum retrieval procedure. Transition dipole moments and Herman-Wallis factors were derived for 15 bands, and a global comparison with theoretical calculations and predictions was obtained. Accuracies for the line intensities ranged between 2 – 3 \% for strong bands and 6 – 30 \% for weak bands. Retrieved line positions were calibrated using CO, HCl and some well-known $^{16}$O$^{12}$C$^{16}$O transitions. For both measured and calculated line positions, the accuracies fell between 0.1 – 1$\times$10$^{-3}$ \wn. Self-broadening was also obtained for a few bands. Complete line lists were generated to support atmospheric remote sensing of the Earth ($\it{e.g.}$, OCO-2 mission), Mars and Venus.\footnote {Research described in this paper was performed at Connecticut College, the Jet Propulsion Laboratory, and California Institute of Technology, and NASA Langley Research Center, under contracts and cooperative agreements with the National Aeronautics and Space Administration.}
