Abstract: The push and pull effect of oxido anion group of the experimentally investigated aryl aryl and aryl alkyl ketyl radicals is interpreted by INDO calculations. From the counter ions in questions (H+ , MgCl+, Ni0, Ni2+) the best agreement between the experiment and the calculations was obtained for Ni2+. The observed nonequivalence of ß protons attached to ketyl group is explained by hindered rotation of CH2 group assuming its proton is in the plane of aromatic ring.
