We present a unified quantitative explanation of the temperature dependence of the drift mobilities of photoinjected electrons in naphthalene for all directions and temperatures. The theory proposed is based on a polaronic description of the charge carriers and the calculational scheme employs site-local states. Excellent agreement of the theory and experiment occurs for known and reasonable parameters.
