| Outline of Final Research Achievements |
Tunneling electrons from a tip of a scanning tunneling microscope induce various dynamical change (includig its orientation change) by a vibrational excitations.Single molecule switching manifests itself in the high and low corrent state controlled by a repeted change of a bias polarity..We developed a first comprehensive theory of action spectrum (reaction rate as a function of an applied bias boltage between a STM tip and single molecule). This allows us to reproduce any reaction spectra. We applied this formula to various motions and rections of single molecules.
