Abstract

The anion radical of the fully aromatic di‐N‐oxide system of azobispyridine N‐oxide was prepared and studied by ESR. Utilising computer simulation and CNDO computation the ESR spectrum was interpreted as follows:

Using appropriate equations the spin densities were calculated at
Ths semi‐quinoidal nature of the radical suggests a possible use as a spin label.
