Figure 4
Positions of X-ray diffraction peaks (black) of pentacene­quinone crystals grown on an Ag(111) surface obtained from rotating GIXD experiments. Top: qy/qx positions of the diffraction peaks; bottom: qz/qx positions. (a) Indexing (blue circles) of a single type of epitaxially oriented crystals grown with the (102) plane parallel to the substrate surface; (b) a second type of crystals grown with the (102) contact plane is indexed (red circles); (c) indexing of all 12 types of epitaxially oriented crystals.
