%X The reactions of the sulfate radical ion (SO4-) were studied by pulse radiolysis of aqueous solutions of aromatic acid and peroxydisulfate ions. With phenylacetic acid, the major reaction is decarboxylation; the resulting ultra-violet absorption spectrum shows that the main product is the benzyl radical, Ph-&#183;CH2, and that only minor amounts of hydroxylation products are formed. However, decarboxylation is unimportant with 4-phenylbutanoic acid and the spectrum has been assigned to the benzylic Ph-&#183;CH-CH2-CH2-COO- radical ion. The same spectrum is obtained if the hydrogen abstraction reaction of the O-&#183; radical ion is used with 4-phenylbutanoic acid to form the latter radical.
