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...

Recent research on classical theories of unimolecular and bimolecular processes in two-mode systems has established the important role of dynamical bottlenecks in non-statistical behavior [ l-51. Previous work on long-time correlations in area preserving maps has identified two types of partial barrier to transport in chaotic regions of phase space [ 6-81. The first are invariant Cantor sets, c...

We investigate quantum transport characteristics of a ladder model, which effectively mimics the topology of a double-stranded DNA molecule. We consider the interaction of tunneling charges with a selected internal vibrational degree of freedom and discuss its influence on the structure of the current-voltage characteristics. Further, molecule-electrode contact effects are shown to dramatically...

We investigate the impact of an external magnetic field on ultra-long-range and ultracold Rydberg molecules. The Born–Oppenheimer potential surfaces are analysed and discussed for different values of the magnetic field strength. The magnetic field provides an angular confinement turning a rotational degree of freedom into a vibrational one. We explore the vibrational dynamics and observe a pron...
