Basics of the time-dependent wave-packet propagation for photodissociations of polyatomic systems

摘要

A brief background on the quantum wave-packet propagation method for the study of photodissociation dynamics of polyatomic molecules is summarized as a short tutorial review. The main emphasis is on reasons to use the wave-packet propagation method, followed by a description about basic considerations for practical application of the wave-packet method to polyatomic molecules. The considerations are divided into six steps in the following sequence: (1) prerequisite information for related states, (2) search for critical points, (3) selection of coordinates and kinetic energy operator, (4) potential energy surface, (5) propagation of wave-packet, and (6) analysis of the propagated results. Limitations of the present review and a very brief perspective are given as concluding remarks. (c) 2016 Wiley Periodicals, Inc.
