  Correlation-driven charge migration initiated by inner-valence ionization
leading to the population of the correlation bands of alkyne chains containing
between 4 and 12 carbon atoms is explored through ab initio simulations.
Scaling laws are observed, both for the timescale of the charge migration and
for the slope of the density of states of the correlation bands. Those can be
used for predicting the relaxation time scale in much larger systems from the
same molecular family and for finding promising candidates for the development
of attochemistry scheme taking advantages of the specificity of the dynamics in
correlation bands of molecules.
