The spectroscopic aggregation number (coherence length) and physical size of the J-aggregates of anionic mesotetrakis(4-sulphonatophenyl)porphyrin (H 4 TPPS 2ร€ ) are controlled by ammonium ion concentration. The contributions of absorption and scattering are determined using the extinction and reson
