The dominant chemical schemes in Venus' atmosphere are believed to have been identified but many significant aspects remain unknown and/or unverified. A key test of the community's current understanding is the molecular oxygen abundance, for which only upper limits have been published. One resource that has not been examined is the archive of past observations using the Fourier Transform Spectrometer on the McMath Pierce Solar Telescope, one of the few instruments capable of making these observations. This project will review the observational archive, identify relevant observations of Venus, examine the archived spectra for evidence of absorption by molecular oxygen, and determine the performance of the instrument for use in requesting future dedicated observing time.
