The Ozone-Iodine-Chlorate Clock Reaction
This work presents a new clock reaction based on ozone, iodine, and chlorate that differs from the known chlorate-iodine clock reaction because it does not require UV light. The induction period for this new clock reaction depends inversely on the initial concentrations of ozone, chlorate, and perchloric acid but is independent of the initial iodine concentration. The proposed mechanism conside...
متن کاملThe Chlorate-Iodine-Nitrous Acid Clock Reaction
A new clock reaction based on chlorate, iodine and nitrous acid is presented. The induction period of this new clock reaction decreases when the initial concentrations of chlorate, nitrous acid and perchloric acid increase, but it is independent on the initial iodine concentration. The proposed mechanism is based on the LLKE autocatalytic mechanism for the chlorite-iodide reaction and the initi...
متن کاملMolecular iodine clock.
We demonstrate a simple optical clock based on an optical transition of iodine molecules, providing a frequency stability superior to most rf sources. Combined with a femtosecond-laser-based optical comb to provide the phase coherent clock mechanism linking the optical and microwave spectra, we derive an rf clock signal of comparable stability over an extended period. Measurements suggest the s...
متن کاملLarge Stable Pulse Solutions in Reaction-diffusion Equations
In this paper we study the existence and stability of asymptotically large stationary multi-pulse solutions in a family of singularly perturbed reaction-diffusion equations. This family includes the generalized Gierer-Meinhardt equation. The existence of N-pulse homoclinic orbits (N ≥ 1) is established by the methods of geometric singular perturbation theory. A theory, called the NLEP (=NonLoca...
متن کاملStudies on the Starch-iodine Reaction
The usefulness of the radiomicrometer in the study of reactions involving a marked color change was indicated in a previous paper (1). It was there shown that the starch-iodine reaction could be investigated in this way. The present paper reports further observations on the reaction, which bear upon the problem of the chemical specificity of some starches and upon the nature of starch-iodide. T...
