✦ Synopsis

Previous theories of exchange narrowing of electron paramagnetic ~~EUMINX spectra are reexamined. [n the case of strong exchange interactions the diagonal mati elements of the dipolar and fine structure interactions are time independent and symmetrization and narrowkg bf the electron resonance specka result from 4 reordering of the magnetic energy levels by the strong exchange interaction. J.&shape caku~tions are given for concentrated Nby (10 mole % C!Q@) and reasonable agwent with experiment is obtained.
