整形飞秒激光脉冲激发是相干二维（2D）光谱学的一种逻辑扩展。在这里，我们结合联合收割机量子控制和信息从二维光谱分析的初始步骤，在三个竞争的反应途径的异构化mercury染料。除了实现控制目标，我们展示了如何激发定制的脉冲可以用来检索光化学信息，是无法访问或实验要求获得与其他方法。
Excitation with shaped femtosecond laser pulses is a logical extension of coherent two-dimensional (2D) spectroscopy. Here we combine quantum control and information from 2D spectroscopy to analyze the initial steps in three competing reaction pathways of an isomerizing merocyanine dye. Besides the achievement of control objectives, we show how excitation with tailored pulses can be used to retrieve photochemical information that is inaccessible or experimentally demanding to obtain with other approaches.
