Abstract

The absorption spectra, and Ep (peak potentials) determined by oscillographic polarography, of five different rhodium(III) complexes have been examined.

From a comparison of Ep values, d-d transitions, and charge transfer peaks proposals have been made to describe the mechanism of reduction of metal complexes.

A series of ligands has been drawn up in which the value of Ep becomes more negative as one moves from left to right across the series. Further, as Ep becomes more negative in crossing the series, the reduction becomes less reversible.
