The dynamics of the highly excited planar carbonyl sulfide molecule (OCS)
is studied using method of Fast Lyapunov Indicators.
The method allows to distinguish strongly chaotic, weakly chaotic, and regular
motions. It gives a good insight into intramolecular dynamics of
this multidimensional system using pictures of the phase space analogous to
Poincare sections for the 2D systems. The evolution of the phase space for the
energies below and at the dissociation threshold is observed and
the main resonant zones are localized. We combine the stability analysis
with a periodic orbit search.
