    • We have not attempted to reproduce the band structure of these materials, nor have we included final state relaxation effects on energies or wave functions or considered photoionization cross sections effects so precise agreement is not expected.

    • This feature is not prominent at XPS energies but is much more clearly seen at low photon energy due to cross section effects. See for example the 40. 8 eV spectrum of VC shown in Figure 10. This fact can be attributed to the different photoionization cross sections of the orbitals in question, with d-orbital ionization having a much higher relative cross section in the 40-50 eV photon energy range than at 1486.6 eV.

    • The C 2s region in the TiC data has greater than anticipated intensity in these 40.8 eV data. We attribute this to the excitation of the Ti MVV Auger feature that is located on the high binding energy side of the C 2s peak. We note that the 40.8 eV photon energy is just below the ionization threshold for the V 3p levels, limiting the impact of resonant PES and Auger electron excitation in the VC data.

    • 3 dipole is unchanged. Our objective here is to show that the magnitude of this interaction is important enough to be considered, particularly for the nitride.
