We present a theoretical and experimental study of the electronic structure of SrRuO 3 after introduction of vacancies. Theoretically, the modeling of non-stoichiometric variations of SrRuO 3 was performed by removing appropriate atoms or their combinations, whereas in the experiments the annealing treatment at moderate temperatures in ultra-high vacuum was applied. At comparison of the obtained results allows us to draw an important conclusion that the formation of oxygen vacancies may be
