Retrieval and tentative indentification of the 3 μm spectral feature in Titan's haze

► Titan's haze 3 μm absorption feature is retrieved from solar occultation data between 127 and 799 km altitude. ► Detailed structure of the 3 μm feature is modeled with absorption bands due to simple ice molecules. ► Possibility of aggregation of these ice molecules onto the surface of tholin-like haze particles is discussed.
