We measure long (2200-4000 A) and short (1450-2200 A) wavelength spectral slopes α (Fν να) for quasar spectra from the Sloan Digital Sky Survey. The long- and short-wavelength slopes are computed from 3646 and 2706 quasars with redshifts in the z = 0.76-1.26 and 1.67-2.07 ranges, respectively. We calculate mean slopes after binning the data by monochromatic luminosity at 2200 A and virial mass estimates based on measurements of the Mg II line width and 3000 A continuum luminosity. We find… Expand
