• Lie algebra
• Vibrational spectra
• C70C8H8

Lie algebraic method is based on the idea of dynamic symmetry, which can be expressed in terms of U(2) Lie algebra. By applying algebraic techniques, an effective Hamiltonian operator can be obtained which conveniently describes the rovibrational degrees of freedom of the physical system. In this framework every C-C bond of the molecule is replaced by a corresponding Lie algebra and finally the Hamiltonian is constructed considering the interacting Casimir and Majorana operators. The fundamental stretching vibrational energy levels of Polymer Phases of C70C8H8 are then calculated using this Hamiltonian to fit the experimental results.
