Abstract
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-, [graphic omitted], and inter-molecular, (RBr∴BrR)+, 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.
