15. Because of the long coherence length and the presence of many scatters, a complicated scattering pattern is observed everywhere on the surface.

18. For other molecules a rigid shift is observed in the spectra acquired on these two surfaces, indicating that NaCl affects the workfunction of the two substrates similarly. (25)

20. Neutral CuPc has an odd number of electrons, hence negatively charged CuPc/NaCl/Cu(100) has two SOMOs.

22. There are slight differences between the two molecules, which are thought to be primarily due to experimental noise associated with the very small changes in apparent height in difference images and the subsequent Laplace filtering.
23. The complicated Moire-pattern of NaCl/Cu(111) seems to influence the difference images of 4NCuPc/NaCl/Cu(111) making their interpretation difficult.
