Description of nonrigid rotation in small atomic clusters
The dependence of the internal dynamics of triatomic van der Waals
clusters on the rate of nonrigid rotation has been studied. The method of
decomposition of the system's motion into orthogonal modes of the motion has
been proposed. Additionally, a new method of separation of the kinetic energy,
captured by the modes, into rotational and vibrational components has been
developed. It has been found that the most significant factor for the chaotic
behavior of the cluster is the partitioning of the vibrational and rotational
energies among the modes
