Vibrational Ir Active Spectra Of Stable Isomers Of Fullerene C-80

Using Hamiltonian-based Lie Algebraic method, the stretching vibrational IR active modes of two stable isomers of fullerene C-80 are calculated. The model appears to describe fundamental stretching modes with less number of algebraic parameters. In this study, the dynamical symmetry group of C-s symmetry is taken into consideration to construct the model Hamiltonian. Casimir and Majorana invariant operators are also determined accordingly. The calculated energies find an excellent exactitude with the simulated PM3 model.
