Abstract
Illumination of ruthenium-catalyzed Belousov-Zhabotinsky reaction decr eases the rotational frequency of spirals at low bromate concentration s but increases the frequency at high bromate concentrations. The effe ctive diffusion coefficient D deduced from the Keener-Tyson relation f or the spirals, D approximate to omega/3k(2), is independent of light intensity (D = 2.5 x 10(-6) cm(2)/s).
