Outline of Final Research Achievements

Time-resolved Faraday rotation measurements were performed using photo-excited state of organic molecules. In ionic liquids, the spin system where the two unpaired electron spins are strongly correlated were observed by using the nano-second laser flash photolysis with the combination of the magnetic field. By the application of Miller-Guy method, the analysis of the stochastic Liouville equations was modified to calculate the time evolution of the complex spin system. Electron spin resonance measurements could not be performed due to the trouble of the spectrometer.
