| Outline of Final Research Achievements |
Raman spectroscopy has been applied to the study of benzophenone in supercritical fluids with hydrogen-bonding ability such as methanol, ethanol, and their mixture with water. Hydrogen boding donating parameters of these solvent have been determined at various thermodynamic conditions. Proton transfer reaction of cyanonaphthol in methanol under various thermodynamic conditions including supercritical state has been measured by the time-resolved fluorescence measurement. The proton dissociation rate and the acid dissociation constant in the electronic excited state have been determined by the analysis based on the diffusion limited reaction model. Obtained parameters were well correlated with the hydrogen bond accepting parameters of the solvent. As a result we have succeeded in getting more deep insight into the reaction mechanism in supercritical fluids with hydrogen-bonding ability.
