  We present dynamics calculations showing how electron-correlation-driven
charge migration occurring in the correlation band of ionized molecules can
lead to a redistribution of the charge increasing the stability of the system.
These calculations offer an interpretation of recent experimental results
obtained for adenine. We discuss the implications of the mechanism for the
development of attochemistry and how it can be understood in the context of the
ultrafast, non-adiabatic relaxation taking place in highly-excited molecular
cations.
