ExoMol1 is a database of molecular line lists that can be used for spectral characterisation and simulation, and as input to atmospheric models of exoplanets, brown dwarfs and cool stars, and other models including those for combustion and sunspots. At high temperatures, the number of lines that must be included to account accurately for the opacity is huge (> 1011 for some molecules), and so absorption cross sections are also provided by the ExoMol project2. The ExoMol website is www.exomol.com.
