| Abstract: | Aggregation of the coloured neutral and cationic forms of rhodamine β in aqueous solution has been studied. The formation constants and absorption of the dimers were determined. The geometric disposition of monomers in both aggregates and the nature of the association forces are discussed. Trimers are not formed. |
