Photochemistry uses light to initiate chemical change. This can often lead to products different from those obtained using usual chemical reagents and heat. Unfortunately, photochemistry is no easier to control than thermal chemistry and often a mixture of producs are obtained. Coherent control aims to use the electric field generated by a laser to direct a chemical reaction. This can be done by using a specially shaped pulse of laser light. How to shape the pulse is a technically difficult problem. How this pulse brings about the control is a theoretically difficult problem. The proposed research is to set up a network of researchers to discuss and solve these problems.

光化学利用光来引发化学变化。这通常会导致产品与使用普通化学试剂和加热获得的产品不同。不幸的是，光化学并不比热化学更容易控制，并且通常会获得产物的混合物。相干控制旨在利用激光产生的电场来引导化学反应。这可以通过使用特殊形状的激光脉冲来完成。如何整形脉冲是一个技术难题。这个脉冲如何带来控制是一个理论上的难题。拟议的研究是建立一个研究人员网络来讨论和解决这些问题。
