They are found between periodic oscillations obtained when [KIO3]0 < 3.00 × 10–2 M and stable steady states when [KIO3]0 > 4.10 × 10–2 M. It was shown that the most chaotic states obtained experimentally somewhere in the middle of this region are in high correlation with results obtained by means of largest Lyapunov exponents and phenomenological analysis based on the quantitative characteristics of intermittent oscillations. |
