The phosphorescent excited states of 1,4-dichloronaphthalene and 1,4-bromochloronaphthalene has been examined by optically detected magnetic resonance (ODMR). Although the crystal structures of these compounds show similarities, the random orientation of the halogens in bromochloronaphthalene causes a large variation in the energy states. The differences in the linewidths of the orientationally disordered crystal are compared to those of the crystal of 1,4-dichloronaphthalene. In addition, dephasing times using pulsed ODMR are reported for the disordered crystal.
