The reorganization energies of the chromophore−antibody complexes are found to be distributed over a wide range. 3PEPS spectroscopy is used to measure the time scales of the reorganization process in one complex. We find that the antibody motions occur on time scales ranging from 75 femtoseconds to 67 picoseconds.
