| Beam scattering studies significantly contributed to our understanding of the dynamics of ion-molecule collision processes. A review of basic elementary ion-molecule processes investigated by these methods will be presented. Examples of case studies will illustrate, in particular, elucidation of collisional mechanism and partitioning of energy in the reaction products from scattering diagrams, angular and translational energy distributions of the reaction products. Collision processes of both cations and dications with molecules will be reviewed. Examples of elementary chemical reactions of singly-charged ions with molecules will include dynamics of impulsive, stripping reactions; long-lived and short-lived complex formation in chemical reactions; hydride-ion transfer reactions; competition between various mechanisms. Also, dynamics of charge transfer (electron exchange) processes and deposition of energy in the reaction products will be discussed. Examples of scattering studies of processes involving dications will concern electron exchange processes in both atomic and molecular systems and the dynamics of chemical, bond-forming reactions of molecular dications with molecules.
