β¦ Synopsis
We report primitive semiclassical rotation-vibrational energy levels for a triatomic molecule, H20, with inclusion of all three vibrational degrees of freedom. Both the Lai-Hagstrom and Hoy-Bunker potential surfaces are used. Vibrational and rotational actions are calculated usinn the fast Fourier transform Sorbie-Handy method. Overall, encouraging agreement with the quantum variational results of Chen, Maessen, and Wolfsberg is found.

A test of a quantum adiabatic treatment of rotational energy for the calculation ofvibrational/rotational energies and dynamics of polyatomic molecules is presented. The approach is given in detail for triatomic systems, where it is shown, in the symmetrictop limit, to be the quantum analog of an ea
Using recently published potential energy surfaces, rovibrational energy levels are computed for the ground electronic states of H O and NO , using three-2 2 Ε½ . dimensional discrete variable representation DVR algorithms. Calculations are presented for H O to demonstrate the accuracy of these algor
