Abstract: K02.00001 : Quantum Scattering of Fullerene C60 with Rare Gas Atoms*
10:30 AM–11:00 AM
The primary goal of the current research is to create a fully quantitative, quantum description of the C60 molecule. A key part of our theoretical study is the understanding of collisional processes of C60 with a buffer-gas of Ar and He atoms, including an analysis of the electronic structure of these complexes, their interaction anisotropy, and the collision-induced rotational and vibrational quenching of C60. In this work, we emphasize the role of the icosahedral symmetry of C60 on its collisional dynamics as potentially transformative feature for molecular spectroscopy. We have shown, for the first time, that scattering quenching times of highly rotational levels of the C60 vibrational ground state are orders of magnitude longer than those that for molecules of lower symmetry. In addition, using the icosahedral symmetry group we predict new optical selection rules.
