Figure 1: Four crystallographically characterized small-molecule complexes are shown (gray, C; dark yellow, S; red, O; bronze, Cu), labeled with the copper oxidation state. Whether it be in the ...

Leo Gross and colleagues examined molecules of pentacene (C 22 H 14) adsorbed on a copper(111) surface and on a sodium chloride film. With the STM, resolving atoms within an adsorbed molecule is ...
