• Thermally stimulated depolarization current (TSDC) has been measured with the pressed discs of p-chloronitrobenzene (pCNB) under various polarizing conditions. The peak temperature at which the maximum current occured in TSDC spectra for pCNB was found always at　-24℃ with the constant heating rate of 1.2℃/min. The depolarization charge (Qd) was dependent on the polarizing field strength, but was independent of the sample thickness. The dipole density calculated by the Debye theory was in fair agreement with the molecular density in the crystal. The peak under TSDC for pCNB may be caused from the orientatioal polarization of the whole molecular rotation in the solid state, The activation energy for the rotation was determined by the intial rising method of Garlick and Gibson, The polarization process was discussed in relation to the crystal structure of the substance.
