The authors report the energy and polarization dependence of resonant inelastic x-ray scattering from Nd{sub 2}CuO{sub 4}. An energy loss feature at {approximately}6 eV is observed in the vicinity of the Cu K-edge. Numerical calculations based on the Anderson impurity model identify this as a charge transfer excitation to the anti-bonding state. The incident polarization is shown to select the intermediate states participating in the resonance process. Resonances are observed at 8,990 eV and 9,000 eV with the incident polarization perpendicular and parallel to the CuO planes, respectively. In contrast to the single-site model calculations, no resonances are observed associated with the {und 1s}3d{sup 10} {und L} intermediate states, suggesting non-local effects play a role.
