| Outline of Final Research Achievements |
I developed near-infrared resonance low-frequency Raman spectroscopy to investigate large amplitude inter- and/or intra-molecular vibrations in resonance with electronic absorptions of delocalized electrons such as solvated electrons, and applied it to several molecular systems. One application is a study of radical cation of a model molecule of benzene dimer. It is found that one of the inter-ring vibrations is observed with strong Raman intensity. This vibration changes the distance of two benzene rings and, thus, couples with the delocalized electron in the two benzene rings. The other application is a study of electronic excited phenylantracenes. Large amplitude anthracene ring vibrations of these molecules are selectively observed because of the resonance enhancement of the delocalized electron on the anthracene rings. This highly-sensitive and highly-selective spectroscopy seems useful to investigate particular inter-molecular vibrations coupled with delocalize electrons.
