Abstract: Evidence is presented for energy transfer from triplet anthraquinone- 2-sulphonate, (3AQS), to pentacyanonitrosylferrate(II), (NP), in aqueous medium at diffusion rate to yield [Fe(CN)5H2O]2- (LSP-ligand substituted product). In the presence of hydrogen donor, 2-propanol, [Fe(CN)4N0]2- (TNF-tetracyanonitrosylferrate(II)) is formed in proportion to [IPA] at the cost of LSP. Ground state AQS does not interfere with the various processes for the quenching of 3AQS and dissolved oxygen does not compete with NP for the quenching of 3AQS, but removes the intermediate radical AQSH responsible for the formation of TNF. Experimental results for the competitive quenching of 3AQS by NP and IPA are shown to fit into the derived rate expression based on the proposed mechanism.
