The theoretical simulation of optical properties of crystals with statistically disordered arrangement of atoms and atomic groups on the basis of point-dipole model

Abstract

With using of point-dipole model the theoretical calculations of main refractive indices and orientation of indicatrix of 18 minerals are performed. The feature of studied minerals is the statistically disordered arrangement of CO3, SO4, SO2, PO4 groups and also separate ions. The optical characters of uniaxial minerals and orientation of indicatrix of orthorhombic and monoclinic minerals, obtained by results of calculations, agree with experimental definitions.
