| Research Abstract |
Surface (hydrogen bonding) structures of water at water/vapor interface pertinent to atmospheric chemical reaction at aqueous aerosols are elucidated based on the theoretical calculations of sum frequency generation spectrum. Experiments have reported the spectrum suggesting the strong hydrogen bonding network characteristic to the water surface. However, the generation mechanism had been little understood for a long time. This study discussed origin of this spectrum by examining the perturbation mechanism of the spectrum at isotope diluted surface. It was found that the characteristic spectrum occurs in spate of the isotope dilution, and the spectrum originates from a strong hydrogen bonding network tangential to the surface.
