title: Electron Transfer and Absorption Spectra of Complexes.
abstract: Occurrence of light saturation in the reaction of thionine (T) with Fe(2+) suggests the existence of T. Fe(2+) complexes practically indistinguishable by their absorption spectra from free thionine; photoreduction seems to occur by electron transfer in such complexes, delayed by more than 10(-5) second after light absorption. Both phenomena must be of general significance.
