Electronic coherences in molecules has emerged as a ‘grand challenge’ in molecular sciences due to the role that electronic correlations and dynamics play in structure and bonding. In the field of attosecond science, electronic coherences can be prepared by attosecond pulses, producing purely electronic wavepackets which persist while the atoms are ‘frozen’ (i.e. a few femtoseconds). Once the atoms unavoidably start to move, the wavepacket could dephase and the electronic coherence would be lost. However, some suggested that nuclear motion could modify or even induce electronic coherences.
