Abstract

The photoreduction in thin layers of Fe^III to Fe^II in the presence of oxalic acid forms spectacular macroscopic patterns. It was studied as a representative of a wide family of chemical systems exhibiting similar behaviour. The formation of these non-equilibrium, dissipative structures, was followed by computerized high sensitivity densitometry under a microscope, revealing, for the first time in these systems, a bifurcation point leading to a packet of transitory states.
