Transient Exciplex Formation Electron Transfer Mechanism
Figure 8
Dependences of (top) and log() (bottom) on for quenching of excited singlet (1) and triplet (2) states of biacetyl by alkenes in MeCN (according to the experimental data of Gersdrof et al. [33]). 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.
