A short review of theoretical models previously used to study single and multiple electron ionization in collisions of bare fast highly charged ions with atomic and diatomic molecular targets is given. Electron emission with simultaneous electron capture by the projectile is also considered. The principal mechanisms producing the different reactions are revisited. It is emphasized that two-center descriptions are necessary for an adequate description of the existing experimental data.The role of electron correlation in the initial bound state and during the collision process is analyzed as well as the presence of effects associated with the two-center character of diatomic molecular targets.
