Growth and adsorption geometry of naphthalene overlayers on HOPG studied by low-temperature scanning tunneling microscopy

► Growth and adsorption geometries of naphthalene on HOPG is investigated by STM. ► STM image of naphthalene molecule reflects the shape of the molecular orbital. ► Tilted configurations of molecules with respect to the surface. ► Substrate-molecule and intermolecular interactions are discussed.
