Photopolarographic studies of some first-row transition elements. Part I

Abstract

Photopolarographic signals over a range of wavelengths within the near-u.v. and visible portion of the spectrum have been obtained for a number of transition-metal ions. The intensity variation of such signals with wavelength enable characteristic ‘spectra’ to be drawn, the intensities being a function of depolarizer concentration. It is suggested that such spectra arise as a result of electronic transitions between levels induced by both photo- and electrode-field excitation of the depolarizer.
