LOCAL FREQUENCY-ANALYSIS AND THE STRUCTURE OF CLASSICAL PHASE-SPACE OF THE LINC LICN MOLECULAR-SYSTEM/

The phase space structure of a generic Hamiltonian model, describing t he vibrational dynamics of the LiNC/LiCN molecular system, is studied using a frequency analysis method. The results obtained for the regula r region constitute a true parametrization of the corresponding invari ant tori on which the trajectories are located. By performing the freq uency analysis locally, much richer information about chaotic trajecto ries is obtained, since it clearly reveals the dynamical characteristi cs of trajectory fragments hidden behind the t --> infinity ergodic pr operty.
