MRI: Development of a High Resolution UV-VIS Coherent Multidimensional Spectrometer

凭借主要研究仪器（MRI）计划的这一奖项，Spelman学院的Peter Chen教授和他的本科生同事将通过广泛升级用于展示高分辨率相干二维光谱的仪器来开发高分辨率UV-VIS相干多维光谱仪，该仪器能够获得复杂分子（电子）光谱中的新信息。这种相干多维光谱仪是独一无二的，因为它能够以比传统的一维方法更高的光谱分辨率分析气相样品。 陈教授和他的团队将通过与埃默里大学、麻省理工学院、芝加哥大学和格鲁吉亚理工学院的研究小组的广泛合作来测试新仪器的能力。陈教授和他的学生合作者正在开发的方法和仪器将有助于确定潜在的分子物理学，使一些分子光谱非常难以理解。 此外，光谱仪还可用于识别大气中重要物种的光化学过程。 与陈教授合作的本科生将学习激光，电子，光学探测器和复杂仪器设计的宝贵技能，为他们在研究生院或更广泛的技术劳动力工作提供良好的背景。

With this award from the Major Research Instrumentation (MRI) Program, Professor Peter Chen from Spelman College and his undergraduate student colleagues will develop a high resolution UV-VIS coherent multidimensional spectrometer by extensively upgrading an instrument that has been used to demonstrate high resolution coherent 2D spectroscopy capable of obtaining new information in complex molecular (electronic) spectra. This coherent multidimensional spectrometer is unique because of its ability to analyze gas phase samples with higher spectral resolution than traditional one-dimensional methods. Professor Chen and his team will test the capabilities of the new instrument through extensive collaboraiton with research groups at Emory University, MIT, the Univeristy of Chicago, and Georgia Tech. The methods and instrumentation that is being developed by Professor Chen and his student collaborators will be useful in identifying the underlying molecular physics that makes some molecular spectra very difficult to understand. In addition, the spectrometer may also find use in identifying the photochemcial processes taking place in atmospherically important species. The undergraduates working with Professor Chen will learn valuable skills with lasers, electronics, optical detectors and the design of complex instruments, giving them an excellent background for work in graduate school or the wider technological workforce.
