Molecules in Titanís atmosphere

Molecules in Titanís atmosphere

Fig. 10.24 . Emission features in the infrared spectrum of Titanís reflected sunlight identify the molecular constituents of its atmosphere. Sharp peaks in this spectrum, acquired from the Voyager 1 spacecraft in 1980, are attributed to methane, CH4, acetylene, C2H2, ethane, C2H6, and more complex hydrocarbon molecules. The wavelength is given in units of microns, or 10-6 meters, abbreviated Ķm.
