Near-edge X-ray absorption spectra of carbon-nitride molecules and solids

Near-edge X-ray absorption fine structure spectra have been calculated for different carbon-nitrogen molecules, clusters and solids. The compounds inv estigated are used to model the chemical bonding in carbon nitride thin fil ms. The molecular and cluster spectra are calculated employing the static e xchange ab initio technique, while the solid state calculations are perform ed with the density functional full potential augmented plane wave method.
