We present JHK near-infrared (NIR) spectroscopy of 25 candidate Type IIquasars selected from the Sloan Digital Sky Survey, using Triplespec on theApache Point Observatory 3.5m telescope, FIRE at the Magellan/Baade 6.5mtelescope, and GNIRS on Gemini. At redshifts of 2 < z < 3.4, our NIR spectraprobe the rest-frame optical region of these targets, which were initiallyselected to have strong lines of CIV and Ly alpha, with FWHM<2000 km/s from theSDSS pipeline. We use the [OIII]5007 line shape as a model for the narrow lineregion emission, and find that \halpha\ consistently requires a broad componentwith FWHMs ranging from 1000 to 7500 km/s. Interestingly, the CIV lines alsorequire broad bases, but with considerably narrower widths of 1000 to 4500km/s. Estimating the extinction using the Balmer decrement and also therelationship in lower-z quasars between rest equivalent width and luminosity inthe [OIII] line, we find typical A_V values of 0-2 mag, which naturally explainthe attenuated CIV lines relative to Halpha. We propose that our targets aremoderately obscured quasars. We also describe one unusual object with threedistinct velocity peaks in its [OIII] spectrum.
