• The rate constant for an electron transfer reaction between triplet eosine and potassium tris(oxalato)cobaltate(III) was estimated. The experimental results from flash photolysis indicate that a transient semioxidized eosine exists in a free state. When a substrate was added to the deaerated eosine and complex solution at an optimum concentration, the original dye was restored by electron transfer from a substrate to the semioxidized eosine, sensitized oxidation occurring efficiently. Choosing indole and its derivatives as a substrate, we have obtained the elementary rate constants of the eosine recovery process.
