摘要：

Three three-state models have been studied to test the capabilities of the Meyer-Miller Hamiltonian studying nonadiabatic photodissociation dynamics, within the framework of the semiclassical initial value representation (SC-IVR). The absorption spectra and the evolution of the electronic populations were calculated using the SC-IVR methodology, and they both show excellent agreement with accurate quantum results. A linearized version (LSC-IVR) was also tested, and it describes the dynamics well for short times but becomes less accurate at longer time, (C) 2001 Elsevier Science B.V. All rights reserved.
