N2 - The relative electron drift mobilities along the three crystallographic directions, at room temperature, in single crystals of 1,4‐dibromonaphthalene were determined by transit time measurements following pulse excitation with a nitrogen laser. The drift mobility was approximately isotropic in the a′b plane with μ ≈ (0.65 ± 0.15) × 10−2 cm2/Vs, whereas its value along the c‐axis was (3.4 ± 0.37) × 10−2 cm2/Vs, or a factor of five times larger. Attempts to measure the hole mobilities proved unsuccessful and is attributed to both extensive trapping at the surface and in the interior of the crystal. The electron drift mobilities are discussed in terms of small polaron transport theory.
