| Research Abstract |
We investigated chemical groups to attach a molecule to metal ellectrode, coupling of tunneling electrons from an STM tip with the degrees of freedom of the molecule such as molecular vibrations and the spin localized inside the molecule, and the relaxation process of vibrationally-excited states formed by tunneling electrons. We found that molecuar motions and reactions take place as a result of the energy relaxation of vibrationally-excited states. In addition, we successfully observed spin excitaion spectra associated with the spins localized in a single molecule.
