For two-component mixtures, Kebarle and Tang observed that the ionization efficiency (i.e., yield of ions per unit concentration) depends strongly on the concentration and nature of other ionizable species and weakly on total concentration of ionized species. In this work, the model used by Kebarle

obtained clearly indicate that the exchange reactions between water and methanol molecules, within the measurements and ab initio calculations on [OV(O 2 )(H 2 O) m -(CH 3 OH) n ] + (m,n: 0-4) peroxo cations have been carried out. coordination sphere of monoperoxo-vanadium complexes, is a conceivable and fast process. This experimental technique allowed the direct observation of the above mentioned species for the first time. The results
