Exposing molecules to ultrashort laser pulses creates electronic wave packets, and therefore, triggers pure electron dynamics in the excited or ionized system. In the case of ionization, these dynamics may manifest as a migration of the initially created localized hole throughout the system and were termed charge migration. Here, we review the theoretical foundation and the most important results obtained in the study of the charge migration phenomenon, as well as give some perspectives for the directions the future studies could go.
