Unlike the classical BZ oscillations, the present oscillations might be considered as radical- controlled rather than bromide-controlled since no substance subjected to bromination was present. Addition of acetone induced dual-frequency oscillations comprised of both the radical-controlled and the bromide-controlled oscillations.展开更多
