A detailed study of the non-Beer's law behavior of the absorption features of the UV spectrum of aqueous K2Pt(CN)4 and BaPt(CN)4 allows a more definitive set of excited-state assignments than previously possible for the monomer.Concentration dependence, quenching and lifetime studies of the several room-temperatuer emission features allow a distinction between fluorescences and phosphorescences and a probable assignment as to the oligomers responsible.Two excited-state absorptions and a long-lived chemical transient are found.
