The infrared emission spectra of highly-irradiated exoplanets are usually modified by atmospheric temperature inversions. Evidence is growing that parmaeters other than irradiation determine whether or not an inversion will form, with at least one highly-irradiated planet not exhibiting an inversion. One possibility, raised by our recent discovery of a planet with an extreme C/O abundance ratio, is that composition plays a key role in dictating the temperature profile of a planetary atmosphere. We propose Spitzer secondary eclipse observations of three exoplanets that we have recently discovered in the WASP project. The host stars of these planets have been found to have the lowest metallicities of all known transiting planets, and our observations will test a prediction that temperature inversions are suppressed in low metallicity atmospheres.
