## Abstract By using calculations rooted in the time dependent density functional theory (TD‐DFT) we have investigated how the lowest energy excited states of a face‐to‐face π‐stacked cytosine dimer vary with the intermonomer distance (__R__). The perfomances of different density functionals have b
