摘要
Decay dynamics of Rg ... I-2(B)(rare gas (Rg) = Ne, Ar, Kr) van der Waals complexes via vibrational and electronic predissociation channels is considered using analytical first-order intermolecular diatomics-in-molecule perturbation theory (IDLM-PT1). Symmetry arguments, quantum spectator model, and quasiclassical simulations confirm qualitatively the validity of IDIM-PT1 diabatic potential energy surfaces and electronic coupling matrix elements.
