Chemical polarisation of electrons in redox reactions

In the system Ti(III)? H₂O₂? RH (RH is isobutyric acid or isopropanol) the concentration and polarisation of the β-radical decreases during the reaction, while the polarisation of the α-radical increases with the decrease of the α-radical concentration. The second fact is not in accordance with Adrian's model of inducing the polarisation in redox systems during the radical recombination process.
