Vibrational Hamiltonian of methylene chloride using U(2) Lie algebra

Vibrational Hamiltonian of Carbonyl Sulphide and Hydrogen Cyanide

“…It operates on the system's wave function, producing the corresponding energy eigenvalues. The basic principle governing our ability to analyse and predict the vibrational frequencies of molecules is of the utmost significance in various disciplines, including spectroscopy and chemical kinetics [5,6,7]. Vibrational Hamiltonian of Carbonyl Sulphide and Hydrogen Cyanide…”

Vibrational Frequencies of Oxygen Difluoride Using Lie Algebraic Model

“…In this model, vibrational Hamiltonian matrix describes the vibrational energies of the molecule. In 1991, onedimesional Lie algebraic method applied for the study of vibrational frequencies of small size molecules by Iachello and co-researchers 1,2 and then this method was subsequently improved in vibrational spectra of medium-size molecules [3][4][5][6][7][8][9][10] .…”

Overtone Frequencies of NO2 using Lie algebraic model

“…In this model, Hamiltonian operator describes the vibrational energies of the molecule. In 1991, Iachello and co-researchers applied U(2) Lie algebraic approach for the analysis of ro-vibrational spectra of small size molecules 1 and then this method was improved in subsequent works to study molecular spectra of polyatomic molecules [2][3][4][5][6][7][8][9][10] .…”
