| Outline of Final Research Achievements |
In the field of biomolecular science, “chirality” is one of the most important properties. All of the biological molecules are alternative enantiomers which show optical activity. An evolutionary origin of such a homo-chirality of biomolecules is still one of the mysteries of nature. So far, the optical activities have been evaluated by the methods in macroscopic scale such as circular dichroism and optical rotation dispersion. For clarifying causality between the optical activities and atomic/electronic configurations, it is quite attractive to investigate the optical properties of chiral molecules at nanoscale. In this research, we construct a combined analysis system for evaluating various properties of a chiral molecular nano-systems, and then proceed mainly to observe the right and left circularly polarized light emission distinctively using scanning tunneling microscopy light emission spectroscopy, tip-enhanced Raman scattering spectroscopy, and so on.
