Time-Frequency Analysis of Classical Trajectories of polyatomic molecules

  title={Time-Frequency Analysis of Classical Trajectories of polyatomic molecules},
  author={Luz V. Vela-Arevalo and Stephen Wiggins},
  journal={I. J. Bifurcation and Chaos},
We present a new method of frequency analysis for Hamiltonian Systems of 3 degrees of freedom and more. The method is based on the concept of instantaneous frequency extracted numerically from the continuous wavelet transform of the trajectories. Knowing the time-evolution of the frequencies of a given trajectory, we can define a frequency map, resonances, and diffusion in frequency space as an indication of chaos. The time-frequency analysis method is applied to the Baggott Hamiltonian to… CONTINUE READING
