| 概 要 | The interaction with water plays a key role for the structure and function of deoxyribonucleic acid (DNA). So far, there is very limited insight into vibrational dynamics of hydration and the couplings governing the interactions of different parts of DNA helix structures with the surrounding water. Femtosecond nonlinear infrared spectroscopy of DNA oligomers provides new and detailed information on the coupling and relaxation of DNA vibrations and on the role of hydrated phosphate groups for energy dissipation. After a brief introduction of the experimental concepts, couplings and dynamics of NH stretching vibrations of adenine-thymine base pairs at different hydration levels will be discussed, followed by an analysis of phosphate-water interactions and energy dissipation processes. |
