We reveal that the ratio of spin–orbit components in X-ray photoelectron Au 4f spectra of titania-supported gold nanoparticles deviates from the statistical ratio 4 : 3 and demonstrates an appreciable dependence on the concentration of Au atoms on the surface of TiO2 support and size of Au nanoparticles.
