抄録

The oxidation potentials of anilin, diphenylamine, p-phenylenediamine, and N-phenyl-p-phenyleenedia-mine derivatives were measured by using polarography under the same condition, and the highest occupied energy levels of these chemicals were caluculated by means of simple L.C.A.O-M.O. method.<br>The oxidation potentials were found to relate linearly to the levels, and the following equation was obtained;<br>Vo=2.3λ-0.95<br>where Vo was the potentials (volt).<br>Now, the energy from the lowest vacant level to the highest occupied level of these chemicals related linearly to the frequencies calculated from ultraviolet absorption. From the results, the reasonance integral β was found to be about 52kcal/mol, when α+2β was adopted as a coulomb integral of nitrogen.<br>From these results, the reaction energy for the reaction between the amine derivatives and ozone was assumed to be lower than 6kcal/mol.
