The Composite Infrared Spectrometer (CIRS) on the Cassini spacecraft has obtained high spectral resolution mid to far-infrared spectra of Saturn's atmosphere. In particular, long integrations were obtained with 0.3 cm-1, unapodized, spectral resolution at 15, 45, 60 and 75 S and high emission angles. These observations are optimal for detecting stratospheric emission from a variety of molecules. We present abundance gradients determined for benzene, carbon dioxide and propane for comparison with previous estimates from ISO and ground-based observations.
