Abstract
The ^13^C n.m.r. spectra of complexes between o‐chloranil and aromatic electron donors were studied. Complexation leads to a general diamagnetic shift of the ^13^C n.m.r. signals for the acceptor (o‐chloranil), but for signals from the ^13^C nuclei in the donors both diamagnetic and paramagnetic shifts are found.
These phenomena are thought to be the result of competing anisotropy and charge‐migration effects. Charge migration in o‐chloranil complexes appears to be more important than in corresponding 1,3,5‐trinitrobenzene complexes.
