General method to simulate molecular processes involving complex interactions between combining subsystems
- 25 Downloads
We consider the transformation process of one molecular subsystem into another (for example, structural isomer-isomer transformation) under the condition of a group of close levels in the first subsystem that have the energy on average coincident with the mean energy of the second subsystem (quasi-degeneration). It is shown that, similar to the previously discussed resonance between two levels of two subsystems, it is also possible in this case to compose an oscillating wave packet leading to a resonant transition from one subsystem to another. The calculation procedure is described that can be applied to atomic ensembles of any complexity with any number of quasi-resonant levels.
