Solute‐solvent interactions of polar molecules generally result in an apparent temperature dependence of dipole moments. Variations of the dielectric constants with temperature of solutions of mono‐ and 1,2‐dichlorobenzene in different apolar solvents confirm the repeatedly observed solvent‐influenced apparent temperature dependence of the dipole moments. An attempt has been made for the first time to interpret these temperature effects on the basis of a statistical (Monte‐Carlo‐Method) and a continuum model. Both models permit the description of the typical curve of the dipole moments as a function of temperature and in addition reproduce the observed effects as to the order of magnitude.
