| Outline of Final Research Achievements |
We have developed a near-IR Raman spectrometer for observing structures of samples at molecular level without photodamage. The mechanism of energy dissipation from photoexcited beta-carotene has been revealed with the spectrometer. Stimulated Raman spectra of photoconductive polymers photoexcited with blue light have been recorded. The results strongly indicate that positively charged states are formed in the polymer in solutions. We have suggested the structure of the charged states and the mechanism of their formation from the peak position of the Raman signal and its time dependence.
