We propose to study the relationship between the optical/UV and mid- to far-IR for normal quasars, dust reddened quasars, and broad absorption line quasars. This project builds on earlier quasar spectral energy distribution (SED) work, mostly using the PG sample of quasars, by extending our knowledge of the IR properties of quasars to higher redshifts and lower luminosities. Our sample will consist of ~40 spectroscopically confirmed quasars (with ~2 Angstrom resolution optical spectra) and ~160 fainter photometrically selected quasars (with accurate photometric redshifts) from the Sloan Digital Sky Survey that are in the Spitzer First Look Survey area. We will extract the IRAC and MIPS photometry for all these spectroscopically confirmed and photometrically selected quasars. Such a sample will contribute significantly to our knowledge of the UV to far-IR SEDs of normal quasars, which will be useful as a basis for comparison with unusual or obscured quasars. In addition we will probe the nature of the reprocessed dust emission through the detailed shape of the IR bump and investigate the AGN-starburst connection with the aid of very long-wavelength data where the starburst contribution is expected to be greatest.
