Abstract
The transient optical absorption bands (λmax= 315 and 345 nm) formed on reaction of ˙OH radicals with 1-chloro-3-iodopropane in N2O-saturated neutral aqueous solutions have been assigned to an OH-adduct formed between iodine atom and ˙OH radicals (t½= 1.5 µs, ε350= 2.46 × 103 dm3 mol–1 cm–1). In acidic solutions, iodine-centred radical cations (λmax= 345 nm, t½= 4.0 µs, ε345= 2.41 × 103 dm3 mol–1 cm–1) are formed at low solute concentrations and dimer radical cations (λmax= 430 nm, t½= 16.0µs, ε430= 6.7 × 103 dm3 mol–1 cm–1) at high solute concentrations. In chloroiodomethane, the ˙OH radicals do not seem to form OH-adducts in neutral aqueous solutions. In acidic solutions, intramolecular radical cation (λmax= 430 nm, t½= 8.0 µs, ε430= 2.63 × 103 dm3 mol–1 cm–1) with oxidized iodine and chlorine is observed. The intermolecular dimer radical cations are formed at high solute concentration (λmax= 500 nm).
