The determination of dipole moments of C60 fullerene has been carried out in benzene, toluene and ortoxylene solutionsunder infinite dilution. It was found that dipole moments are 1.0 D, 1.8 D and 2.27 D in toluene, benzene and ortoxylene, respectively.

It means that there are isolated C60 molecules in toluene solution but associated clusters with constant stoichiometry in benzene and ortoxylene solutions.
