Recombination of Geminate (OH,eaq-) Pairs in Concentrated Alkaline Solutions: Lack of Evidence For Hydroxyl Radical Deprotonation
Full text linkPicosecond dynamics of hydrated electrons and hydroxyl radicals generated in
200 nm photodissociation of aqueous hydroxide and 400 nm (3-photon) ionization
of water in concentrated alkaline solutions were obtained. No deprotonation of
hydroxyl radicals was observed on sub-nanosecond time scale, even in 1-10 M KOH
solutions. This result is completely at odds with the kinetic data for
deprotonation of OH radical in dilute alkaline solutions. We suggest that the
deprotonation of hydroxyl radical is slowed down dramatically in concentrated
alkaline solutions.Comment: 12 pages; 2 figures; submitted to Chem. Phys. Let
