Extended Data Fig. 1: Conformational transformation of CoTPP on Cu(100).
From: Visualizing vibrational normal modes of a single molecule with atomically confined light
a, An imaging sequence starting at −0.5 V is followed by repeated scans at –12 mV. The size of the images is 35 × 35 Å2. The pressing scanning condition at −12 mV leads to planarity of the phenyl groups. b, Optimized geometry of a free CoTPP molecule and flat geometry of an adsorbed CoTPP molecule with artificially flattened phenyl rings. c, Lattice registry of the flat CoTPP and the marker CO molecule, which adsorbs on the copper on-top site.
