ALLER AND MARGO F. ALLER Astronomy Department, University of Michigan, Dennison Building, Ann Arbor, Michigan 48109 Electronic mail: hugh@astro.lsa.umich.edu, margo@astro.lsa.umich.edu Received 1994 January 6; revised 1994 March 28 ABSTRACT We present radio to submillimeter-wave continuum spectra of 44 bright, compact extragalactic radio sources with flat spectra at centimeter wavelengths ("blazars"). Infrared J, H, and K flux densities are added to the spectra of six of these objects. These spectra are useful in comparisons of x-ray and {gamma}-ray measurements with the multiwaveband properties of blazars. A number of the objects have been detected as strong, hard {gamma}-ray sources by the Compton Gamma Ray Observatory (CGRO). The millimeter-wave spectra of the {gamma}-ray bright blazars we observe are flatter on average than for the sample as a whole.
