Scientific paper

Infrared spectroscopy of familiar rest-frame optical emission lines in four high luminosity z ≍ 2.3 QSOs is presented. Q0933+733, Q1225+317, Q1246-057, and Q1413+177 were observed in the H-band with a resolution of 1600 km/s, covering the spectral region around Hβ, including the [O III] λλ5007, 4959 lines and optical Fe II complexes. In comparison to low redshift, lower luminosity QSOs, the high redshift QSOs have weak [O III], small Balmer equivalent widths, and much more Fe II emission.
