Research Themes
Studies on the structure and dynamical behavior of the bio-related moleculer complexes by high-resolution spectroscopy
I observe hydrogen-bonded molecular complexes, multilple molecules bonded with one another by hydrogen bonding, through spectroscopic experiments in gas-phase independent systems, and by investigating molecular structures and qualities related to dynamic behavior, I intend to explain various phenomena in liquids and water solutions at the molecular level. More specifically, I aim to investigate the effects of hydrogen-bonded complexes, including protein, and explain higher-order structure formation processes and the basic characteristics of function manifestation, focusing on the small-model molecules that are the basic components of biomolecules.
High resolution Spectroscopic study on unstable (transieut) Molecules.
I conduct high-resolution molecular spectroscopic research on highly reactive transient molecules such as those called radicals. These unstable molecules form and exist in special environments, including space, at high temperatures, and in plasma, and provide clues for examining important information about the environment through observation of their spectrum. They also attract attention as reaction intermediates. In addition, since electronic motion is significantly reflected in the molecular energy and quality of these molecules, its precise research will further our understanding of the basic theories in molucular science.
