This article analyzes the problems of polydispersity in electro-optics. It
examines the application of the regularisation technique in order to determ
ine distribution functions of colloidal particles and macromolecules on ele
ctric dipole moments, on polarisability anisotropy values, and on rotary fr
iction coefficients. It also includes two additions to the regularisation t
echnique. (C) 1999 Elsevier Science B.V. All rights reserved.
