Abstract

Electronic excited state is one of the common forms in which atoms,
molecules and ions exist in the nature. Study on the characters and
dynamics behaviors of the molecular excited states, such as energy levels,
lifetimes, predissociation and auto-ionization, as well as on their
electronic structures, is not only a significant topic related to chemical
reactions and chemical dynamics, but also one of the frontiers in the field
of atomic and molecul
