The sign and magnitude of the intramolecular magnetic coupling between the two triplet nitrene units through the benzanilide chromophore have beep studied by temperature dependence of their EPR fine structures; The results that the interactions are ferromagnetic in the m,p' and m',p isomers and antiferromagnetic in the p,p' and m,m' isomers were corroborated by semiempirical CI calculations.
