With support from the Major Research Instrumentation (MRI) Acquisition Program, the Department of Chemistry at the University of Portland will acquire a Fourier Transform Infrared/ Fourier Transform Raman Spectrometer (FT-IR/FT-Raman). The instrument will be used to investigate interactions between solutes and solvents in supercritical fluids. One system to be studied will be Rhodamine B dissolved in the co-solvent system of acetonitrile and supercritical carbon dioxide. Study of other solvent systems and dyes is planned.Infrared and Raman spectroscopy measure the vibrational frequencies of molecules. These frequencies are characteristic of the atoms and how they are connected in a molecule. This analytical tool is a sensitive probe of the structure of the molecules and how the surrounding environment influences them. This can help to better understand how to more efficiently extract dissolved substances, process fuels and chemicals, and improve manufacturing processes using chemicals. The instrument will enhance teaching and research of undergraduates at the University of Portland.

在主要研究仪器（MRI）采购计划的支持下，波特兰大学化学系将获得傅里叶变换红外/傅里叶变换拉曼光谱仪（FT-IR/FT-拉曼）。 该仪器将用于研究超临界流体中溶质和溶剂之间的相互作用。 其中一个待研究的体系是将罗丹明B溶解在乙腈和超临界二氧化碳的共溶剂体系中。 红外和拉曼光谱测量分子的振动频率。 这些频率是原子的特征以及它们在分子中的连接方式。 这种分析工具是分子结构以及周围环境如何影响它们的灵敏探针。 这有助于更好地了解如何更有效地提取溶解物质，处理燃料和化学品，并使用化学品改进制造工艺。 该仪器将加强波特兰大学本科生的教学和研究。
