Popis:	Absorption and emission spectroscopy, utilizing theoretical group analysis, was used to investigate the nature of triplet states of chrornate and bichromate ions in aqueous solutions. The complex kinetics observed for the quenching of phosphorescence is explained by competition of emission and rapid exchange of energy between triplet sublevels. Quenching of phosphorescence is observed in concentrated chromate ion solutions. The dimer nature of the bichromate ion prevents intermolecular exchange of energy between ions in view of the existence of a more effective intraionic energy transfer.
