Transient absorption spectra at indicated times after the pulse radiolysis of N₂O-saturated benzene with solubilized 1 mM of retinal (A), and representative kinetics of the formation and decay of retinal cation radicals monitored at 610 nm (B–G) after pulse radiolysis in the absence and presence of α-tocopherol (α-TOH), β-tocopherol (β-TOH), γ-tocopherol (γ-TOH), and δ-tocopherol (δ-TOH).
