Abstract: ESR method has been used to study the dynamics during oxidation process of some acidic phosphate (phosphonate) oxovanadium complexes in THF. The effects of temperature, concentration and nature of complexes on reaction rate and reaction reversibility have been examined. Dynamical parameters-reaction order, reaction rate constant and the activation energy of reaction were calculated.
