Show affiliationsIn this paper we investigate the electronic properties of single molecules by means of low-temperature scanning tunneling spectroscopy (STS). We focus on C60 molecules deposited on a Au(111) surface at different substrate temperatures and mixed with two different hydrocarbons. In this way we change the fullerene interaction with the surface and/or the dipolar response of the molecular neighborhood to charging events. We explore the dependence of the energy level alignment on the molecular surroundings. The results confirm an already established picture in photoelectron spectroscopy.
