| Outline of Final Research Achievements |
To observe a circular dichroism (CD) of gas-phase molecules, we developed the apparatus of a bow-tie cavity ringdown spectroscopy (CRDS) that are constructed by four highly reflective mirrors and electrospray ionization (ESI) to generate gaseous non-volatile molecules. We applied ESI to a cyanine dye molecule in water/methanol solution, and were able to produce the dye molecule that is embedded in micro-droplet. By applying CRDS to the dye molecule in droplet, we succeeded to measure the absorption spectrum of electronic transition, which has a peak at 660 nm. In this study, we understood that highly stabilized apparatus for ESI source should be developed, if we observe a terribly weak CD signal.
