| Outline of Final Research Achievements |
Many biological cofactors, such as light-absorbing chromophores in photoreceptors, are intrinsically planar molecules. A protein environment, however, causes structural distortions of the cofactor, and such structural changes can lead to a modulation of chemical properties of the cofactor to maximize its biological activity. In this project, we have constructed a near-infrared excited Raman optical activity (ROA) spectrometer with a scattered circular polarization scheme. Using this state-of-the-art ROA spectrometer, We found that a hydrogen out-of-plane ROA band provides a spectroscopic ruler for the out-of-plane distortion of the chromophore that is embedded in a protein environment.
