Calculation of Vibrational Energies of AlH2 Using U(2) Lie Algebraic Approach

Abstract

Using the U(2) Lie algebraic approach, it is determined that the vibrational energies of the aluminumdihydride (AlH2) molecule up to the fifth overtone and reported the combinational bands up to the third harmonic.In this approach, the algebraic parameters and operators are used to represent the Hamiltonian operator to calculate the vibrational energies.
