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.

通过主要研究工具（MRI）计划的奖项，Spelman College和他的本科生同事的Peter Chen教授将通过广泛升级一种仪器来开发高分辨率UV-VIS相干多维光谱仪，该仪器用于获得高分辨率相干2D光谱镜头，以获得高分辨率相干2D相光谱，以获取具有新信息的复杂信息（Electexmult in Complectermult（Electextraqual）。这种一致的多维光谱仪是独一无二的，因为它的能力比传统的一维方法可以分析光谱分辨率更高的气相样品。 Chen教授及其团队将通过与埃默里大学，麻省理工学院，芝加哥大学和佐治亚理工学院的研究小组的广泛合作来测试新乐器的功能。 Chen教授及其学生合作者正在开发的方法和仪器将在识别使某些分子光谱很难理解的基本分子物理学方面有用。 此外，光谱仪还可以找到用于识别大气重要物种中发生的光化学过程的用途。 与Chen教授合作的本科生将通过激光，电子设备，光学探测器和复杂乐器的设计学习宝贵的技能，从而为他们提供了研究生院或更广泛的技术劳动力的良好背景。
