We show that the ARPES spectra for emission from the bonding as well as the antibonding Fermi surface sheet in Bi$_2$Sr$_2$CaCu$_2$O$_8$ (Bi2212) possess remarkable site selectivity properties in that the emission for photon energies less than 25 eV is dominated by $p \to d$ excitations from just the O-sites in the CuO$_2$ planes. There is little contribution from Cu electrons to the ARPES intensity, even though the initial states at the Fermi energy contain an admixture of Cu-$d$ and O-$p… Expand
