We present H and K spectra (showing redshifted H?, H? and [O III] emission lines) of three radio-loud and three radio-quiet quasars with redshifts z >~ 2, which were obtained using CGS4 on UKIRT The [O III] ?? 4959 + 5007 lines are too weak to allow accurate determination of the redshift of the forbidden lines. The observed Balmer decrements are consistent with enhancement of H? due to collisional excitation.
