A new model of the light-harvesting antenna (core complex) of purple photosynthetic bacteria is proposed based on excitonic interactions in circular aggregates of bacteriochlorophyll molecules. The calculated absorbance difference spectra of circular aggregates demonstrate all special features observed in the experimental spectra of purple bacteria. In particular, the absorption changes with high amplitude of bleaching at the long-wavelength side of the absorption band at different excitation energy are predicted.
基于细菌叶绿素分子环状聚集体中的激子相互作用，提出了一种紫色光合细菌光捕获天线（核心复合体）的新模型。计算得到的环状聚集体的吸光度差光谱展示了在紫色细菌实验光谱中观察到的所有特殊特征。特别是，预测了在不同激发能量下，吸收带长波侧具有高漂白幅度的吸收变化。
