Laboratory of Molecular Spectroscopy (IMRAM)
We are looking for good students, who are interested in something new, something strange, and something useful. The students synthesize molecules, run spectroscopic measurements, analyze the data, and find out new phenomena. We like cheerful and active students in all countries who love Japan.

Abstract
Correlations between structural & dynamic properties and functions of composite molecules including metal complexes, excited states, and proteins are studied by means of advanced EPR. Techniques such as highly time-resolved & pulsed high frequency EPR, high MW power & 2D pulsed EPR are now being developed in our laboratory.
1. Studies of excited triplet states and ion pairs by highly time-resolved high field EPR.
2. Correlation of structure and function in biological systems (PS I/II, troponin) using EPR.
3. Development of advanced EPR (high MW power, pulsed, and high frequency) techniques.
