MIT Laser Research Facility

这个由化学、材料研究、物理和生物仪器以及麻省理工学院激光研究设施资源部门参与的续展奖项将为13名化学和物理系教师提供核心支持。启动一批新的协作研究项目。在物理化学方面，这些包括开发调制光谱技术，将其应用于二维光学光谱和自由基检测；探索高激发水平下的单态和三态分子势面；以及涉及振动激发的大气物种的碰撞过程。基础物理研究将包括原子-腔量子电动力学和里德堡原子中量子混沌的探索。在材料科学中，将研究量子晶体、表面功能化的量子粒子以及聚合物薄膜的声学性质。包括甲烷单加氧酶和核糖核苷酸还原酶在内的酶模型系统以及光合作用和视觉色素中的光传导机制的研究将是生物和无机化学研究的重点。所有这些项目都需要该设施提供的高分辨率、多激光和/或超快脉冲设备。%该设施还为学生提供实践经验和高级光谱技术培训。研究人员的互动导致了新的合作和研究计划，如果没有这个设施，这些合作和研究计划就不会存在

This renewal award, with participation by the Divisions of Chemistry, Materials Research, Physics and Biological Instrumentation and Resources made to the MIT Laser Research Facility will provide core support for thirteen Chemistry and Physics faculty. A number of new collaborative research projects will be started. In physical chemistry, these include development of modulated-spectroscopy techniques, with application to two dimensional optical spectroscopy and free radical detection; exploration of singlet and triplet molecular potential surfaces at high levels of excitation; and collision processes involving vibrationally excited atmospheric species. Fundamental physics studies will include atom-cavity quantum electrodynamics and explorations of quantum chaos in Rydberg atoms. In materials science, quantum crystallites, surface-functionalized quantum particles, and acoustic properties of polymer films will be investigated. Studies of enzyme model systems, including methane monooxygenase and ribonucleotide reductase, and the mechanisms of light transduction in photosynthesis and visual pigments will be the focus of research in biological and inorganic chemistry. All of these projects require the high resolution, multiple-laser, and/or ultrafast-pulse equipment provided by the facility. %%% This facility also provides students with hands-on experience and training in advanced spectroscopic techniques. The interaction of the investigators leads to new collaborations and research programs which would not exist in the absence of the facility
