ULTRAFAST SPECTROSCOPY


Hikaru
Kuramochi

Observation and elucidation of ultrafast molecular dynamics by advanced time-resolved spectroscopy
Tracking the molecular dynamics from the electronic and structural viewpoints is essential for deep understanding of chemical reactions. To this end, we develop new ultrafast spectroscopic methods based on basic knowledge on the light-matter interaction and state-of-the-art laser technology. Using these advanced spectroscopy, we aim to observe, understand, and control new fundamental phenomena of reactive molecules.

INTERFACE SPECTROSCOPY

Developments of novel inteface-selective nonlinear spectroscopies and elucidations of molecular mechanisms of interfacial phenomena
Emergences of novel experimental techniques often open new doors for finding new phenomena as well as unknown mechanisms, especially for microscopic elucidations. In our group, by developing new techniques based on the even-order nonlinear optics, we investigate the structures and dynamics of molecules at interfaces. Our studies are opening up a new field of interfacial science.

SINGLE-MOLECULE SPECTROSCOPY

Ishii

Development of novel single-molecule methods and application to elucidate complex behavior of biomolecular systems
The single-molecule spectroscopy group is engaged in the development of new methods of single-molecule fluorescence spectroscopy and related photon data analysis. By utilizing the developed methods, we investigate the complex behavior of biomolecular systems, such as proteins, nucleic acids, and lipid membranes. Through the integrated approach of laser spectroscopy, biophysical chemistry, and statistical data analysis, we pursue creating a new field of molecular science.
