Vibrational spectra of H2O and CF4 molecules using Lie algebraic approach

In this paper, we introduce one dimensional vibron model to analyze the fundamental, overtone and combination modes of CF 4 molecule and both stretching, bending vibrational mode of bent H 2 O molecule up to first overtone with few algebraic parameters. Using the model Hamiltonian, we reported here better results for the vibrational spectra of H 2 O. Our analysis suggests some reassignments of levels and predicts location of states in case of CF 4 molecule which was not yet observed.
