Electrooplical Method Of Dterminalion Of The Permanent Dipole Moment Of Colioidal Particles

~qO tYges of rectangular electric fields (Rl - and R2~field)rnare produced by a specially constructed generator. IHhen Rl ~rnfield acts on the caracitor plates between ~Ihich is thernsolution to be investigated, the colloidal particles rotaternand modulate the intensity of light that passes through thernsolutioIl. The electric dipole moment is given by thernexpressionrn6KTT ~n{ (~ - 1) + 2 1 t(~· .- 1) 11rnFT ornR2-field is used for the determination of the time ofrnrelaxation T. '['he electric field E is choosen and the para~rnmeters b and TO are measured. Although specimens of diffe~rnrent chemical and physical nature are investigated therndipole moment per tmit area .1rn0rnis almost the same for allrnspecimens .I lies in the ranae (1.4 - 2.0) x 10-4 CGSE
