Selective excitation, at room temperature, in the long wavelength absorption tail of the photosystem I antenna complexes, known as light harvesting complex I, induces pronounced pre‐equilibration fluorescence from the directly excited pigment state. This has allowed determination of the fluorescence band shape of this low energy photosystem I chlorophyll antenna state, at room temperature, for the first time. The emission maximum is near 735 nm. The remarkable band width (55 nm) and asymmetry have never been previously reported for chlorophyll a states.
