Pulse radiolysis study on radical cations of alkyl bromides in aqueous solutions

H. Mohan,   D. K. Maity  and  J. P. Mittal  

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 λmax 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.
