Figure 11: Dependences of l o g 𝑘 Q (top) and log ( 1 / 𝑘 Q 1 / 𝑘 D i ) (bottom) on Δ 𝐺 E T for quenching of triplet states of various quinones by methylbenzenes in MeCN (circles) and CH2Cl2 (squares) (according to the experimental data of Hubig and Kochi [14]). Best plots are shown for simulation of the experimental dependence by (3) ( 𝜆 = 0 . 1  eV) (dash line) and by concatenated mechanism (16) (solid line). Dotted line shows thermodynamic limit for ET.
