This article analyzes electron energy-loss near-edge fine structures of the SrO(SrTiO3)n=1 Ruddlesden-Popper system and of the parent compounds SrTiO3 and SrO by comparison with calculations. For that, the fine structures have been experimentally recorded of Ruddlesden-Popper films deposited by the sol-gel method. Moreover, extensive density-functional theory (FPLO code) a computations have been performed. It is shown that the appearance and shape of the experimental O-K and Ti-L2,3 fine structure features result from the crystallography-dependent electronic structure of the investigated oxides, which display technologically interesting dielectric as well as lattice-structural properties.
