Multiple quantum (MQ) Spin-polarized EPR spectra of fullerene C60 dissolved in glassy ortho-terphenyl was measured in the temperature range of 80 - 240K. The temperature dependence of the spectra was successfully simulated using the model of fast pseudorotation of 3C60 in a potential created by the surrounding solvent molecules. The strength of this potential was estimated at different temperatures. Near 240K this potential was found to decrease remarkably.
