✦ Synopsis
At a certain temperature the malonic acid Belousov-Zhabotinsky reaction, which is simultaneously catalyzed by ferroin and cerium ions, can exhibit regular transitions between the ferroin oscillating and the cerium oscillating states. We believe that this is the first demonstration of transitions between two distinct oscillatory states in a closed system. The differences between ferroin and cerium catalysis are briefly discussed and the observed dynamic behaviour is qualitatively explained in terms of the Field-K&i%-Noyes theory.
