Abstract:

The collision energy transfer processes involving nonadiabatic transition play important roles in atmosphere, interstellar, combustion chemistry, and chemical lasers. Since such energy transfer processes usually involve a variety of nonadiabatic effects between multiple electronic states, theoretical studies on the diabatic potential energy surfaces and dynamics calculations are very challenging. In this paper, we review the calculation methods of the diabatic potential energy matrices, the diabatic potential energy surfaces, the conical intersections, and spin-orbit couplings in the nonadiabatic energy transfer dynamics, focused on two important nonadiabatic energy transfer processes of C(1D)+N2 and I(2P3/2)+O2a1Δg). The dynamics of both two nonadiabatic energy transfer processes are discussed and summarized. The importance of the nonadiabatic effects in these processes is also revealed.

Key words: Nonadiabatic effect, Spin-orbit coupling, Conical intersection, Potential energy surface, Quantum dynamics (Ed.: Y, K, S)
