XUV

We are developing approaches to image electron transfer using x-rays in a variety of systems ranging from isolated gas phase molecules, substrate supported inorganic catalysts and two-dimensional materials. In this proposed research, we will develop methods to prepare photoexcited wave packet superpositions with a high degree of coherence and assess the role of coherent electron motion as it applies to all three critical aspects of the photochemical process of molecular energy transduction: 1) coherent electron dynamics prepared at the origin of photon absorption, 2) image charge migration across chemical bonds and molecular coordinates, and 3) transformations in matter that are not thermodynamically accessible. These types of ultrafast motions ultimately dictate the fundamental processes that drive all chemical reactions.
