Abstract
The ESR and EDRS methods were used to study the effect of adsorption of water and oxygen molecules at room temperature on the valence transformations and coordination transformations of Cr(III) and Cr(V) ions in a tetrahedral ligand environment and Cr(V) ions in square-pyramid coordination, ions that were formed on the surface of SiO2 after vacuum heat treatment of CrO3/SiO2 samples at 1173 K.
