MULTIFREQUENCY EPR STUDY OF PHOTOSYNTHETIC CENTERS IN BACTERIA

集光过程中天线的EPR最新测量 细菌光合作用中心的复合体可能指示电子 在许多相同的站点之间跳跃。理论计算(J. 首页--期刊主要分类--期刊细介绍--期刊题录与文摘--文摘内容太棒了。103：2873-2881,1995) 为分析多频连续波EPR谱提供了依据 提取“跳跃率”。我们已经得到了变量 质子化和氢化的温度(4-273K)数据 在X波段和W波段使用设施收集光的复合体 IERC。现在已经对数据进行了分析。进一步测量 包括恩多在内，都在计划之中。

Recent EPR measurements on antennae in the light-harvesting complexes of bacterial photosynthetic centers may indicate electron hopping among many equivalent sites. Theoretical calculations (J. Tang, S.N. Dikshit, J.R. Norris, J. Chem. Phys. 103:2873-2881, 1995) provide a basis for analyzing multifrequency CW EPR spectra and extracting the "hopping" rate. We have already obtained variable temperature (4-273k) data from both protonated and deuterated light-harvesting complexes at X- and W-band using facilities at the IERC. Now the data have been analyzed. Further measurements including ENDOR are planned.
