The direct observation of molecular orbitals of molecules adsorbed onto surfaces is an extremely useful way to understand adsorbate–adsorbate and adsorbate–substrate interactions. In this chapter, I report the visualization of the valence orbitals of NO molecules on a Cu(001) surface with STM at 6 K. For a NO monomer on the surface, the valence \(2\pi ^*\) orbital remains doubly degenerate, because the molecule is bonded to a highly symmetric site of the surface. I also observed that the NO dimers on the surface spontaneously react to yield O adatoms at 78 K. The results indicate that NO/Cu(001) shows higher catalytic reactivity for NO reduction than the NO/Cu(110) system.
