In this work we reconsider the problem discussed by Caldeira and Leggett (CL), and generalize their results for a quantum oscillator coupled bilinearly to a reservoir with dense discrete spectrum of harmonic oscillators. We show that for such systems

A simple model for ultrafast and efficient photoisomerization reactions is presented. In this model, the relevant region of the potential results from double crossing of two harmonic 1D diabatic potentials with opposite curvature. The eigenvalue prob

This paper completes the development of the perturbative instanton approach (PIA), presented in previous papers of this series, as a rigorous semiclassical method for the calculation of the tunneling dynamics in multidimensional potential energy surf

The six-dimensional torsion-vibration Hamiltonian of the H2O2 molecule and its H/D- and 18O/16O-isotopomers is derived. The Hamiltonian includes the kinetic energy operator, which depends on the tunneling coordinate, and the potential energy surface

Twenty one dimensional potential energy surfaces (PES) and the tunneling coordinate dependent kinematic matrices of malonaldehyde and of several of its isotopomers (D, 13 C) are constructed in the low-energy region ( −1 ) using quantum-chemical dat

A universal approach to description of quantum dynamics of nonrigid molecules and molecular complexes is outlined. The method includes reconstruction of the potential energy surface using data of quantum-chemical calculations of the geometry and eige

The perturbative instanton approach (PIA) developed previously [Benderskii and co-workers, Chem. Phys. 219 (1997) 119; 219 (1997) 143; 234 (1998) 153] is generalized to multidimensional Hamiltonians in which the potential is non-separable and the kin
