| Abstract
| - The bromate−hypophosphite−acetone−Mn(II)−Ru(bpy)32+ batch oscillator was recently suggested for studyingtwo-dimensional pattern formation. The system meets all major requirements that are needed for generationof good quality traveling waves in a thin solution layer. The serious drawback of using the system for studyingtemporal and spatial dynamical phenomena is its unknown chemical mechanism. In order to develop amechanism that explains the observed long-lasting batch oscillations the bromate−hypophosphite−acetone−Mn(II)−Ru(bpy)32+ oscillator was revisited. We studied the dynamics both in the total system and in somecomposite reactions, and kinetic measurements were carried out in three subsystems. From the new experimentalresults we concluded that the two oscillatory sequences observed in the full system are originated from twooscillatory subsystems, the Mn(II)-catalyzed bromate−hypophosphite−acetone and the Ru(bpy)32+-catalyzedbromate−bromoacetone reactions. Here we propose a mechanism which is capable of simulating the dynamicalfeatures that appeared in the complex system.
