With support from the Major Research Instrumentation (MRI) Program, Prof. Peter C. Chen of Spelman College will develop a high resolution universal resonance Raman probe for studies in chemistry and materials science. The probe, which would use nonlinear resonance Raman spectroscopy for the selective identification and studies of species, would be able to provide resonance Raman spectra over an exceptionally broad range of input wavelengths (220-1800 nm). Furthermore, this instrument will be able to provide this information with very high spatial, spectral and temporal resolution. The universal resonance Raman probe will be useful for non-intrusive probing of challenging but important samples such as high temperature, highly reactive gas phase samples that may contain complex mixtures and interfering species. Such challenging conditions are found in chemical vapor deposition (CVD) and related processes for creating new high-tech materials. Undergraduate students from groups that are underrepresented in the sciences (Spelman College is an historically black women's college) will help design, construct and test this new instrument on a CVD system. These CVD experiments will be carried out in collaboration with scientists at Microcoating Technologies, a private company that specializes in combustion CVD.

在主要研究仪器（MRI）计划的支持下，Peter C.斯佩尔曼学院的陈将开发一种高分辨率的通用共振拉曼探针，用于化学和材料科学的研究。 该探测器将使用非线性共振拉曼光谱学对物种进行选择性识别和研究，将能够在非常宽的输入波长范围（220-1800 nm）上提供共振拉曼光谱。 此外，该仪器将能够提供具有非常高的空间、光谱和时间分辨率的信息。 通用共振拉曼探针将用于非侵入式探测具有挑战性但重要的样品，例如高温、高反应性气相样品，其可能包含复杂的混合物和干扰物质。 这种具有挑战性的条件在化学气相沉积（CVD）和用于制造新的高科技材料的相关工艺中发现。 来自科学领域代表性不足的群体（斯佩尔曼学院是一所历史上的黑人女子学院）的本科生将帮助设计、建造和测试CVD系统上的这种新仪器。 这些CVD实验将与Microcoating Technologies的科学家合作进行，Microcoating Technologies是一家专门从事燃烧CVD的私人公司。
