Abstract
We present mid-infrared spectra of 5 submmillimeter galaxies at redshifts z = 0.65 − 2.38 taken with the Infrared Spectrograph aboard the Spitzer Space Telescope. Four of these sources have strong PAH features and the strength of these features are consistent with these galaxies being dominated by star formation. The other source displays a Mrk 231-type broad emission feature at restframe ~8 μm that does not conform to the typical 7.7/8.6 μm PAH complex in starburst galaxies, suggesting a more substantial AGN contribution.
