In this chapter, STM-IET spectra of NO monomers and dimers on Cu(110) and Cu(001) surfaces are reported. Frustrated rotational and translational modes were detected as a peak-and-dip structures in the spectra.The experimental observations were also studied theoretically by electronic structure calculations for the role of vibrational excitations in the tunneling process.Considering symmetries of valence orbitals and vibrational modes of the molecules, the intensity of the observed IETS signals were successfully explained in a qualitative manner.
