Excited-state absorption arising from transitions between singly and doubly excited exciton components in strongly coupled photosynthetic antennae profoundly influences the absorption difference spectra observed in pump-probe spectroscopy. Model calculations of the absorption difference spectrum in the BChl a-protein complex from P. aestuarii are compared with the experimental spectrum.
