Collisional energy transfer in highly vibrationally excited C70

Quasiclassical trajectory calculations of the energy transfer of highly vibrationally excited C70 colliding with helium and argon have been performed. From these calculations, the character of collisional energy transfer (CET) between C70 and rare gas atoms was provided by comparing the results with the related systems such as benzene, toluene and azulene. It was found that deactivation of C70 was significantly less than in toluene and azulene. These results were explained by the temporal dependent analysis of every trajectory.
