Article abstract of DOI:10.1039/ft9938900477

The transient optical absorption bands formed on reaction of *OH radicals with 1,m-dibromoalkanes and n-alkyl bromides in acidic aqueous solutions have been assigned to intra-, <*>, and inter-molecular, , radical cations, respectively.Depending upon R, these radical cations exhibit an optical absorption band in the 385-450 nm region.Increases in the chain length and electron-releasing power of R results in a red shift of λ_max and a decrease in the lifetime.These radical cations are strong oxidants and oxidize various substrates with bimolecular rate constants of the order of 10⁹ dm³ mol^-1 s^-1.
