Scanning tunneling spectroscopy (STS) was used for investigation of rectification properties of molecules with spatial asymmetry. The molecules of cetyltrimethylammonium derivatives of 10-molibdo-2-vanadophosphate-anions [PMo10V2O40]^﹣5 (CTMVA) were adsorbed on a surface of pyrolytic graphite (HOPG). Consequently, both good diode properties and J(V)-curves reproducibility of the film were revealed. The validity of the single-level model for the evaluation of the system parameters is discussed.
