中文摘要
研制了一套用于测量和控制激发态振动的超快光谱系统,并将其应用于光合作用初级过程的能量传递。我们已经获得了新的结果,S* 激发态类胡萝卜素使用重建LH 1复合物。利用飞秒受激拉曼光谱观测到了光捕获过程中的瞬态振动。用多脉冲激发成功地控制了LH1的能量转移。
英文摘要
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.
