Abstract

Abnormal fluctuations of chemiluminescence intensities have been observed in the CH2(COOH)2−BrO3−Ru(bipy) 2+,3+3 system, when catalyst concentrations are insufficient for stable self-oscillations to be generated. Amplitude distribution of these fluctuations (reaction “noise”) are of the “bell” shape, which is typical for the normal Gaussian distribution. Their nature is similar to the large-scale fluctuations that are the “nuclei” for dissipative structures.

Abstract

Обнаружены аномально большие флуктуации интенсивности хемилюминесценции в системе CH2(COOH)2−BrO −3 −Ru(bipy) 2+,3+3 при концентрациях катализатора, недостаточных для возникновения устойчивых автоколебаний. Распределение амплитуды этих флуктуаций (“шума” реакции) имеет колоколообразный вид, характерный для нормального гауссовского распределения. Вероятно, по своей природе они близки к тем крупномасштабным флуктуациям, которые являются “зародышами” диссипативных структур.
