Attosecond charge migration in a neutral molecule has been observed to decohere within approximately 10 fs. However, this does not mean that the electronic coherence is irreversibly lost, as the charge migration is observed to revive after 40–50 fs. These findings have the potential to enable laser control of photochemical processes.
