PERIODIC ORBIT ANALYSIS OF MOLECULAR VIBRATIONAL SPECTRA - 1/1 RESONANT COUPLED MODES

摘要

In this paper we analyze the quantum density of states for a model molecular vibrational Hamiltonian describing two coupled anharmonic (Morsel oscillators. Periods of classical periodic orbits as a function of energy and coupling parameter are extracted directly from the quantum spectrum using the Gabor transform. We are able to identify the quantum manifestation of the local-to-normal transition, and of resonant bifurcations of periodic orbits. (C) 1995 American Institute of Physics. [References: 60]
