✦ Synopsis

The validity of the "transfer diffusion theory" developed by Ruff and Friedrich is examined by measuring the conductivity of N, N-dimelhylformamide solutionscontaining anthracene and itsanion which undergo a rapid electron exchange. The contribution of this process to the molar conductivity of the solution is calculated from the experimental results by using the Onsager equation and the Walden rule. It obeys the requirement of the theory that it should be proportional to the concentration of anthracene.

From the proportionality coefficient and the available data for the electron exchange rate constant, together, the distance of electron jump at the moment of exchange is estimated.
