FORMATION OF RADICAL CATIONS OF CHLOROBENZENE IN AQUEOUS-SOLUTIONS - A PULSE-RADIOLYSIS STUDY

The transient optical absorption bands (lambda(max) = 290, 475 nm) for med on the reaction of OH radicals in an acidic aqueous solution of ch lorobenzene are assigned to the solute radical cation. It decays (475 nm) by first-order kinetics with k = 1.8 X 10(4) s(-1). The extinction coefficient (475 nm) is determined to be 7.87 X 10(3) dm(3) mol(-1) c m(-1).
