Figure 12: Dependences of (top) and log () (bottom) on for quenching of excited singlet states of cyanoaromatic compounds by methoxybenzenes and methylnaphthalenes in MeCN (according to the experimental data [15]). Best plots are shown for simulation of the experimental dependence by (3) ( eV) (dash line) and by concatenated mechanism (16) (solid line). Dotted line shows thermodynamic limit for ET.
