| Research Abstract |
Ultrafast spectroscopy system for measurement and control of vibrations in excited states has been developed and applied to energy transfer in primary process of photosynthesis. We have obtained new results about the S* excited state in carotenoid using reconstituted LH1 complexes. The transient vibrations in the light-harvesting process have been observed by femtosecond stimulated Raman spectroscopy. The energy transfer in LH1 has been successfully controlled by multipulse excitation.
