摘要:
A separation of intra and intermolecular degrees of freedom, based on an invariant phase-space hyperangular momentum approach, is proposed as useful alternative to the usual roto-vibrational mode analysis. Two partitions (hyperspherical and projective) of the kinetic energy are here illustrated for simulations of chemical reactions and shown interesting to analyze caloric curves of clusters. Case studies are Ar-13 and Ar-38. (c) 2005 Elsevier B.V. All rights reserved.
