We present a k-dependent study of the single hole states in Sr2CuO2Cl2. We demonstrate that the
controversial "1 eV peaks" in the high Tc's are quasiparticles derived from the same O 2p states as the
Zhang-Rice (ZR) singlets, but of different symmetry and intensity in those regions of the Brillouin zone
where the hybridization with the correlated Cu 3d states vanishes by symmetry. We use this new source of
information to estimate the quasiparticle weight of the ZR singlets, discuss the quasiparticle line shape, and
suggest a strong k dependence of the self-energy.
