A theoretical model is presented to account for the physical mechanism of energy transfer from antenna molecules to the reaction centers in photosynthesis. The energy transfer is described by a generalized transport equation or "master equation". The solution of this equation for the proposed model gives a relationship between the antennae interaction energy and the transfer rate. The results are shown to be in agreement with inter-antenna transfer rates calculated from experimental fluorescence lifetimes. Previous theories were based either on the Förster mechanism, which is valid for very small interaction energies, or an exciton model valid for very large interactions, but experimental results seemed to indicate that the actual situation was intermediate between these two. The Förster theory and the exciton model are limiting cases of the master equation.
提出了一个理论模型来解释光合作用中能量从天线分子转移到反应中心的物理机制。能量转移由一个广义传输方程或“主方程”描述。针对所提出模型求解该方程，得出了天线相互作用能与转移速率之间的关系。结果表明与根据实验荧光寿命计算出的天线间转移速率一致。先前的理论要么基于对非常小的相互作用能有效的Förster机制，要么基于对非常大的相互作用有效的激子模型，但实验结果似乎表明实际情况介于这两者之间。Förster理论和激子模型是主方程的极限情况。
