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.

有了这个化学键合中心（CBC）第一阶段，第二步奖，化学部和数学和物理科学理事会多学科活动办公室共同支持加州尔湾大学的Shaul Mukamel的研究，他将领导一项涉及加州大学尔湾分校和加州大学圣巴巴拉分校研究人员的合作努力。该CBC将使用综合的实验和理论方法，以单原子分辨率实时探测分子的内部工作。 这些研究的目标是表征化学中的基本事件，例如单个分子的氧化和还原，化学键的形成和断裂，以及分子之间的电荷转移和传输。 这些调查将通过提供化学事件发生时的延时序列，在最基本的层面上提供化学过程的真实空间和实时画面。 这种能力将为科学家和公众提供一个新的视角来研究分子事件。 化学键合中心的设计是为了集中创新的合作努力，解决一个“大问题”，这将导致化学或化学与其他科学的接口的重大进展，并将有可能吸引广泛的科学和公众的兴趣。
