| Research Abstract |
Infrared spectroscopy was applied to methanol-water mixed clusters to probe microscopic picture of water-alcohol mixture. At the first stage, we studied neutral and protonated methanol clusters, of which structures have not been well established in large sizes. We demonstrated that the clusters form simple cyclic structures (or bicyclic structures in the protonated clusters) in the size range of 10 - 50. At the second stage, we studied structures of methanol-water mixed clusters and confirmed that clathlate structures in which a water molecule is surrounded by methanol molecules are formed at specific sizes.
