8Ps for native and NaBH〓 chemically modified reaction centers, and the transfer process from H〓 to the final electron acceptor Q〓 occurs in about hundreds of picoseconds. On the other hand, the energy transfer from excited B was obviously slowed down in the pheophytin-exchanged RC. By considering the change of free energy of ion pair P〓Phe〓, it could be expected there might exist alternative pathway of charge separation and electron transfer in pigment-exchanged reaction center. In addition, the influence of acid environment on the ultrafast dynamics of reaction center was also experimentally observed, which shows an evident difference from that of in native RC, and further investigation should be carried out to elucidate the origination.

在色素置换后的反应中心中，以B为起点的能量传递较天然RC的情况明显减慢，约在450fs左右，考虑到置换后的反应中心中P的自由能有所提高以及其仍然保持的光化学活性，这一较慢的能量传递也可能预示着还存在着其它的能量传递通道；另外，还对酸性处理的反应中心中的超快光动力学过程进行了尝试性的研究，发现由于色素分子的聚集以及蛋白环境的改变，BChl分子的激发态动力学过程有着明显不同于天然反应中心的情况。
