Vibrational spectra of distorted structure Macro & Nano molecules: An algebraic approach

Abstract

Using the Lie algebraic method the vibrational frequencies of 97 resonances Raman lines (A 1g + B 1g + A 2g + B 2g ) and 38 infrared bands (E u ) of octaethylporphyrinato-Ni (II) and its mesodeuterated and 15 N-substituted derivates and Fullerenes C 60 and Cv 70 of 7 vibrational bands are calculated using U(2) algebraic Hamiltonian with four fitting algebraic parameters. The results obtained by the algebraic technique have been compared with experimental data; and they show great accuracy.
