Interactions between the Molecules of Different Fullerenes

Abstract

Generalizing the procedures of Girifalco and of Verheijen et al. and using results of the preceding work it has been derived the interaction potential between the molecules of different fullerenes Cn and Cm at orientationally disordered (high-temperature solid and gaseous) phases. We have calculated the coefficients for interactions of the C60 molecule with the molecules of higher fullerenes from C70 to C96 and with the smaller one, C36. The dependence of the minimum point and of the depth of the potential well on the numbers of the atoms in the molecules m and n has been investigated.
