Two-Dimensional Free Energy Surfaces for Electron Transfer Reactions in Solution
Figure 1
Potential energy curves of a D-A pair
with eV ( eV) in a nonpolar solvent
().
The broken and solid curves represent the diabatic and adiabatic curves,
respectively. The parameter values assumed, the molecular radii of D and A, are
3 Å, and in (9) are 0.23 eV at 4 Å and 1 Å,
respectively. Plotting is made down to Å which is smaller than Å. This is not meaningless because
D and A are often not spherical but planar and can approach to distances
shorter than .
