| Description | An orientation factor for a colloidal particle with positive and negative sites has been obtained by considering the differences of electrophoretic velocity of the particle under an action of electric field. A simple model that many spheres are linearly connected with each other is assumed and the electrophoretic velocity of each part of the particle is estimated from the number of unoccupied sites calculated by Langmuir's adsorption isotherm. The orientation factor we obtained depends on the number of site and the equilibrium constant for adsorption and can be used to explain the field dependence of electric birefringence of polyelectrolytes.
