Bolletta and Balzani (1982) observed oscillating chemiluminescence in a B-Z reaction with tris (2,2 -bipyridine ruthenium (II), Ru(bpy)3+, [First used by Demas and Diemente J. Chem. Ed. 50 (1973) 357]. This is the first example of oscillating chemiluminescence in a B-Z reaction.

Chemiluminescence is also observed in the Ru(bpy)3 catalyzed oxidation of malonic acid, the Belousov-Zhabotinskii reaction. By using a continuous flow technique, oscillating chemiluminescence can be both observed and controlled. ... 

Oscillating chemiluminescence has been observed in the H2O2/KSCN/ CuS04/NaOH/luminol system there are two types of oscillation, and the low-intensity mode may involve the reaction of superoxide with luminol. A simplified mechanism for the methylene-blue/HS /02 oscillation in a CSTR has been proposed. Experimental and modeling structures of oscillation in the C102/l2/malonic acid system show that the oscillations are not due to autocatalysis but to self-inhibition in the ClOf/I reaction. A study of the oxidation of hexacyanoferrate(II) by bromine is concluded to involve the formation of Brf as an intermediate, formed in the first step. The aerobic oxidation of NADH catalyzed by horse radish peroxidase... 

Other compounds whose autoxidation and chemiluminescence have been studied are tetralin [18-20], cumene and ethylbenzene [20,21]. Oscillating chemiluminescence during such oxidations has also been observed [22].

A water-cooled sampling probe of internal diameter 1 mm and external diameter 5 mm with a 3-meter long heated line was used to measure concentrations of unburned hydrocarbon (flame ionization detector, Analysis Automation, 520) and NOj (chemiluminescence analyzer, Thermal Environment Instruments, 42) at the combustor exit on a wet basis. The former, measured to a precision of the order of 1 ppm, was used to ensure complete consumption of fuel within the duct, and the latter with a precision of around 0.2 ppm was used to quantify the effect of oscillations on NOj. emissions. 

Rauhut and coworkers were the first to obtain rate constants from emission kinetic studies and to verify the dependence of kobsi and kobsi on the concentration of the base catalyst and on hydrogen peroxide, respectively. Schowen and coworkers , using TCPO, H2O2 and DPA, with triethylamine as catalyst, observed an oscillatory behavior in emission experiments and proposed a mechanism involving the formation of two HEIs (involved in parallel chemiluminescent reactions) to explain it. Other authors have also observed a similar oscillating behavior but have explained it as a complex...

Toby and Ulrich (1980) studied oxidation of CO by ozone and under certain experimental conditions observed undamped oscillations in chemiluminescence. 

For one of the surfaces (surface a ), a very sharp peak is seen at a reagent translational energy of 4.7 meV. Finally, Fig. 8 contains results for an electronically nonadiabatic collinear model of the chemiluminescence reaction Ba 4- ON2 BaO(X, a H) 4- N2 reaction. Once more, pronounced oscillations are observed in these curves.
