Multiplicity in a Chemical Reaction with One-Dimensional Dynamics

Measurements on the Belousov-Zhabotinskii reaction in a stirred flow reactor reveal, beyond a period-doubling cascade, a sequence of periodic states that is different from the "U (universal) sequence" found in recent experiments on diverse systems. Particular periodic states occur in three different parameter ranges rather than one range as in the U sequence. However, the order of periodic states found here is in accord with a one-dimensional single-parameter map constructed from the laboratory data.
