Abstract (from CDS):

We present observations of the starburst galaxy NGC 7714 with the Infrared Spectrograph on board the Spitzer Space Telescope. The spectra yield a wealth of ionic and molecular features that allow a detailed characterization of its properties. NGC 7714 has an H II region-like spectrum with strong polycyclic aromatic hydrocarbon emission features. We find no evidence for an obscured active galactic nucleus, and with [NeIII]/[NeII]~0.73, NGC 7714 lies near the upper end of normal-metallicity starburst galaxies. With very little silicate absorption and a temperature of the hottest dust component of 340 K, NGC 7714 is the perfect template for a young, unobscured starburst.
