| Research Abstract |
The aim of this study is to establish water-surface cluster chemistry, based on the experimental data. An ultraviolet-excitation confocal fluorescence microscope is newly developed to confirm that organic molecules form cluster on the water surface even if the molecules have a smaller molecular weight than 300 and are spread with an extremely low surface density. A semi-confocal microscope has been designed and developed, which covers excitation wavelength ranging from 250 nm to 500 nm to observe surface-selective excitation spectra. Polycyclic aromatic hydrocarbon was selected as target molecules. The semi-confocal microscope utilizes excitation with monochromated high-power Xe-lamp in the total internal reflection geometry. Performance of the microscope was evaluated. Surface-specific spectra were observedfor some chemicals including pyrene. New method for determining surface-pH was proposed. Some of the results are presented in academic domestic and international conferences and the other parts were summarized as matters to be under further investigation.
