Abstract
The energy transfer( ET ) and electronic excitation transport( EET ) are two important ultrafast primary processes in PS II reaction centers. All kinds of ultrafast laser spectroscopy techniques are used in the dynamic study on PS II reaction center1. Although many results have been obtained, much debate still exists on the structure and function of the reaction center, the physical mechanism and rates of the ET and EET2. In this paper we report some experimental results on the ultrafast dynamic study on the ET and EET in the PS II reaction center. The PS II reaction center, D1/D2/cyt-b559 complex, is isolated and purified from the spinach, which contains 4 or 5 Chia molecules, 2 pheoa molecules, 1 β-carotene molecule.
