N2  - Solutions of benzyl chloride and benzyl alcohol in cyclohexane were subjected to pulse radiolysis. The absorption of the band at 307/318 nm (22A2 excited state) of the benzyl radical increased with solute concentration as expected over the range from to 10-5 to 10-1 M. On the other hand, the absorption of the 258-nm band (42B2 state) decreased with concentration and is zero at 10-2 M. It is considered that the population of radicals in the vibrational or electronic sub-levels of the ground state from which the 42B2 transitions take place is affected by an interaction or association process dependent on solute concentration. Extinction coefficients (l. mol-1 cm-1) for the benzyl radical in 10-5 M solution are 9000 at 318 nm, 4500 at 307 nm and 41000 at 258 nm.
