Scientific paper

Analysis of the 2.5 to 5.0 micrometer spectra of Io using detailed laboratory studies of plausible surface ices is described. The results show that Io's surface most likely contains H2S and H2O mixed with SO2. The 3.85 and 3.91 micrometer bands in the Io spectra can be assigned to the v1 fundamental mode in H2S clusters and isolated molecules in SO2 ice. The 2.97 and 3.15 micrometer bands coincide with the v3 and v1 vibrations of clusters of H2O molecules complexed with SO2. The observations are well matched by the spectra of SO2 ices containing 3 percent H2S and 0.1 percent H2O which has been formed by condensation onto a 100 K surface. The shifts and splitting of the absorption bands seen in the Io spectrum and the fact that solid H2S is observed in the surface material of Io at temperature and pressure conditions above its sublimation point can only be explained by the mixed molecular ices model.
