Algebraic method for determining the potential energy surface for nonlinear triatomic molecules Original Research Article

The potential energy surfaces of nonlinear triatomic molecules are determined by the U(4) algebraic method. The combination coefficients in the Hamiltonian are gotten from fitting the spectroscopic data. The molecular properties, such as, force constants and dissociation energies, are obtained in terms of the potentional energy surfaces. The results for the SO2 molecule are in good agreement with the experimental results and other theoretical results.
