Reduced-dimensionality quantum bound state treatment of hydrogen-bonded clusters: Torsional vibrational manifold of the water trimer

Research output: Contribution to journalArticle


The reduced-dimensionality quantum bound state treatment of hydrogen-bonded clusters was presented. The three-dimensional bound state calculation of the intermolecular torsional energy levels of (H2O)3, (D2O)3, other isotopomers and quantum (3+1)-dimensional torsional-stretching calculations were reviewed. Results showed that the equilibrium geometry and separability of harmonic vibrational modes were not applicable to the vibration-rotation-tunneling (VRT) dynamics of highly fluxional and anharmonic weakly bound molecular species.
