Time-Dependent Treatment of SVRT Model for Polyatom–Polyatom Reaction
This chapter presents a time-dependent quantum wavepacket treatment of the semi-rigid vibrating rotor target (SVRT) model for studying reaction dynamics between two polyatomic molecules. The present work is an extension of previous work on the SVRT model for an atom–polyatom reaction and can be considered as a generalization of the exact diatom–diatom reaction model. Numerically exact dynamics calculation of the present SVRT model for a polyatom–polyatom reaction involves seven degrees of freedom. The detailed mathematical treatment and implementation of the time-dependent wavepacket method for a polyatom–polyatom reaction are described.
