Orbital Map Movie (VIDEO) Ohio University This video is under embargo. Please login to access this video. Caption This movie reveals different energetic positions, and the shapes of unoccupied orbitals of [Eu(pcam)3X]2+ and [Eu(pcam)3]3+. It is created from 8000 dI/dV spectroscopic maps acquired over a pair of [Eu(pcam)3X]2+ - [Eu(pcam)3]3+ complexes at ±2000 mV range with 1 mV interval between the consecutive frames. This movie shows controlled clockwise rotation of a [Eu(pcam)3X2]+ complex on Au(111) surface when a negative electric field is applied from the STM tip.
