Various chemical reagents were fed continuously into a continuously stirred tank reactor to perturb the Belousov-Zhabotinskii system. The resulting bifurcation diagrams each contain multiple curves separating regions with different types of dynamical behavior. These very complex diagrams can be used as fingerprints of the perturbing chemical mechanism. Essentially the same bifurcation structures were observed under the addition of formaldehyde and sodium bromite, indicating the same mechanism. The effect of bromomalonic and hypobromous acids was also found to be nearly identical; the slight differences between their fingerprints is explained by the effect of bromine, which contaminates the HOBr. Finally, the effect of added bromide is shown in another bifurcation diagram.
