This research, part of the Experimental and Computational Physical Chemistry Programs, is in the area of Chemical Kinetics. It will theoretically and experimentally investigate oscillatory chemical reactions. Mechanistic investigations of a number of oscillatory systems will be performed. These studies will employ both classical experimental methods and fast reaction techniques such as stopped-flow as well as extensive computer simulation. Rate laws and rate constants will be determined for several elementary processes that play important roles in these systems. Coupled chemical oscillators will also be investigated including those that arise when two oscillators interact either via mass flow or through common chemical species. New computation methods will be used to explain the experimentally obtained results including the effects of stirring and mixing, the propagation of waves of chemical reaction under the influence of a gravitational field, the influence of electric fields on the propagation of chemical waves when ions play an important role in the chemistry of the reaction, and reactions in which the reaction time varies stochastically.

这项研究是实验和计算物理化学项目的一部分，属于化学动力学领域。它将从理论上和实验上研究振荡化学反应。一些振荡系统的力学研究将被执行。这些研究将采用经典的实验方法和快速反应技术，如停止流动以及广泛的计算机模拟。将确定在这些系统中起重要作用的几个基本过程的速率定律和速率常数。耦合化学振子也将被研究，包括那些当两个振子通过质量流或通过共同化学物质相互作用时产生的振子。新的计算方法将用于解释实验得到的结果，包括搅拌和混合的影响，引力场影响下化学反应波的传播，当离子在化学反应中起重要作用时电场对化学波传播的影响，以及反应时间随机变化的反应。
