ODMR on the delayed fluorescence (DF ODMR) of b-9, IO-dichloroanthracene (DCA) exhibits triplet excitons, whose signals could be recorded between 1.2 and 45 K. The exciton line broadening of 4 MHz has inhomogeneous character below 1.8 K, where propagation is coherent. At higher temperature the lines

β¦ Synopsis
The mobility of holes in the alpha phase of 9, lO-dichloroanthraccne is isotropic with a value at 300 K of 3.8 I 0.2 cm2 V-r 5-l and a temperature dependence given by T-n where n = 2.4.

The photodissociation of iodine has been studied in the@ phase by Iaser fIash photoiysis. The decrease of the quantum yield with increasing ethane and propane pressure has been intirpreted in terms of the cage effect. As the tempemture is increased a less pronounced czge effect is observed\_ The tre
