With this Chemical Bonding Center (CBC) Phase I, Step II award, the Division of Chemistry and the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate jointly support the research of Shaul Mukamel, of the University of California Irvine, who will lead a collaborative effort involving researchers from UC Irvine and UC Santa Barbara. This CBC will use an integrated experimental and theoretical approach to probe the inner workings of molecules in real-time with single atom resolution. The goal of these investigations is to characterize elementary events in chemistry such as the oxidation and reduction of a single molecule, the making and breaking of chemical bonds, and charge transfer and transport among molecules. These investigations will lead to a real-space, real-time picture of chemical processes at the most fundamental level by providing time-lapse sequences of chemical events as they occur. This capability will provide a new perspective into studies of molecular events for scientists and the public at large. The visual component of the science to be developed by this CBC makes it particularly well suited for broad public dissemination.Chemical Bonding Centers are designed to focus innovative collaborative efforts that address a "big problem" which will lead to a major advance in chemistry or at the interface of chemistry and other sciences and will have the potential to attract broad scientific and public interest.

借助这个化学键合中心（CBC）第一阶段，第II级奖，化学系和数学和物理科学局的多学科活动办公室，共同支持加利福尼亚大学Irvine大学Shaul Mukamel的研究，他们将领导UC Irvine和UC Santa Barbara的研究人员的协作努力。该CBC将使用集成的实验和理论方法，通过单个原子分辨率实时探测分子的内部工作。 这些研究的目的是表征化学中的基本事件，例如单个分子的氧化和还原，化学键的产生和破坏以及分子之间的电荷转移和转运。 这些研究将通过提供化学事件的延时序列，从而导致最基本水平的化学过程的实时实时图片。 这种能力将为科学家和整个公众的分子事件研究提供新的观点。 该CBC将要开发的科学的视觉组成部分使其特别适合广泛的公众传播。化学粘合中心旨在集中精力的创新协作努力，以解决“大问题”，这将导致化学和其他科学界面的重大进步，并有可能吸引广泛的科学和公众利益。
