The mobility of photoinjected holes in smectic-B liquid crystals as measured by time of flight shows an electric field dependence at low fields. This dependence is suspect, for whether the mobility rises or falls with field depends on the method by which the photocurrent transients are analyzed. In the context of the multiple trapping model, a general formalism is developed for analyzing the transients, in which the distribution of traps may be determined under the assumption that the Einstein relation between the mobility and the diffusion constant is obeyed. For the smectic-B liquid crystal, this distribution is adequately described by a Gaussian of depth 100 meV and width 50 meV.
