The status of laboratory spectroscopic data for exoplanet characterisation
missions such as EChO is reviewed. For many molecules (eg H2O, CO, CO2, H3+,
O2, O3) the data are already available. For the other species work is actively
in progress constructing this data. Much of the is work is being undertaken by
ExoMol project (www.exomol.com). This information will be used to construct and
EChO-specific spectroscopic database.Comment: Experimental Astronomy, accepte
