Abstract:
Charge transfer in ion-molecule reactions is quite common, but the accompanying energy transfer process has not been well understood. Recent state-resolved molecular beam experiments shed valuable light on the microscopic mechanisms in such nonadiabatic systems. In this talk, we discuss some of our recent theoretical studies of collisional dynamics in prototypical charge transfer systems and interpretation of experimental observations.1-3
