Figure 4

The electron density difference map of 7DE and of 7DE-ITPT with their corresponding radical (Panel (A)), and the spin density of the 7DE-ET and the 7DE-ITPT-ET radical (Panel (B)). In constructing the electron density difference map, the radical formed immediately after the electron transfer has taken place is used, and the electrons in the radical have not yet relaxed. The difference map shows where the electron is lost. The electron density map of the radicals depicted in panel B is of the stable radical.
