| Outline of Final Research Achievements |
We have constructed the systems to clarify the response mechanism of biomolecules to the application of an external electric field. The constructed IR electroabsorption system was optimized to observe the electric field effect of molecules in solution state with a very small change of a magnitude of 10-6. We have measured the electric field effects on the IR absorption spectra of fatty acids in solution state and observed the broadening of the spectra in the C = O stretching and C - H stretching bands region, which is due to the so-called Stark shift. The anharmonicity of each vibration mode can be discussed based on the magnitude of the observed broadening.
