Abstract

The spectrum of Saturn has been recorded between 2.3 and 15 mu m, on June 13, 1996, with the grating mode of the Short-Wavelength Spectrometer of ISO (Infrared Space Observatory). The resolving power is about 1500 and the sensitivity is better than 1 Jy. As compared to Jupiter, the spectrum of Saturn is characterized by a higher signal at 3 mu m, as compared to the 2.75 mu m value, and a weaker signal in the 5-mu m region, due to Saturn's lower temperature. The main differences between the Jupiter and Saturn spectra are mainly due to a lower NH_3 mixing ratio and higher mixing ratios of PH_3, CH_4, C_2H_2 and C_2H_6 in Saturn's atmosphere as compared to their values in Jupiter. A preliminary modelling will be presented and estimates of the mixing ratios and/or vertical distributions of minor atmospheric species will be inferred.
