Polar molecules and solvents

If both polar and nonpolar molecules are present, a dipole-induced dipole interaction may occur. For this situation, the strength of association may be represented by Eq. 4, which is dependent on both the dipole moment of the polar molecule, and the polarizability of the nonpolar component. Once again, this relation does not include the interactions between the polar molecule and solvent molecules ... 

The Inclusion of Dielectric Saturation. The phenomenon of dipolar association in solution has attracted attention since 1928 (21). A substantial body of experimental evidence has since been accumulated. Both the self-association of polar molecules and solvent-solute multipolar complexation (including that of transition states) have been detected and studied ...
