Summary A computer solution of the Pauli Master Equation is used to study the fluorescence quantum yield of a two‐dimensional random host‐trap‐anti‐trap system. Calculations predict that both the quantum yield and prompt fluorescence lifetime from photosynthetic units increase as pigment heterogeneity increases. From the temperature dependent action spectrum of fluorescence the pairwise Forster transfer rate is predicted to decrease with decreasing temperature.
