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.

在重大研究仪器（MRI）计划的支持下，斯佩尔曼学院的Peter C. Chen教授将开发一种用于化学和材料科学研究的高分辨率通用共振拉曼探针。 该探针将使用非线性共振拉曼光谱来选择性识别和研究物种，能够在极其广泛的输入波长（220-1800 nm）范围内提供共振拉曼光谱。 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。 通用共振拉曼探头可用于非侵入式探测具有挑战性但重要的样品，例如可能含有复杂混合物和干扰物质的高温、高反应性气相样品。 这种具有挑战性的条件存在于化学气相沉积 (CVD) 和用于制造新型高科技材料的相关工艺中。 来自科学领域代表性不足的群体的本科生（斯佩尔曼学院是一所历史上的黑人女子学院）将帮助设计、构建并在 CVD 系统上测试这种新仪器。 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 的私营公司。
