Research Abstract |
We have investigated the occupied and unoccupied levels for nano-link molecules. The nuclear motion of molecule in the excited electronic state is detected as the change of the vibronic structure. The pump-photon energy dependence of the two-photon photoemission spectrum revealed that the photoexcitation process cannot be interpreted by a simple energy level scheme, and point to further understanding of excitation process. By comparative experiments on spectroscopy and atomic level microscopy, correlation between the structure of molecular assembly and electronic structure is clarified.
