Purchase of a UV-VIS Spectrophotometer (Chemistry)

紫外/可见（UV/VIS）光谱学是一种利用吸收紫外线来探测分子结构的技术。紫外/可见分光光度计的购置对于改善现代化学系的研究和教学环境至关重要。佛罗里达国际大学化学系将使用该仪器，该仪器是在化学共享仪器计划的资助下购买的，用于加强以下化学领域的研究：1)气体和凝聚相中分子紫外/可见光谱的温度依赖性2)人类黄斑色素中类胡萝卜素的分离和鉴定3)配位化合物的热化学4)卟啉的竞争螯合；紫外/可见分光光度计将为这所将提高有才华的黑人和西班牙裔学生的参与作为其主要目标之一的大学提供重要的研究和教学仪器。

Ultraviolet/Visible (UV/VIS) spectroscopy is a technique that uses absorption of ultraviolet light to probe molecular structure. The acquisition of an UV/VIS spectrophotometer is crucial for enhancing the research and teaching environment of the modern chemistry department. The Department of Chemistry of Florida International University will use the instrumentation, purchased with the help of an award from the Chemistry Shared Instrumentation Program, to enhance research in the following areas of chemistry: 1) Temperature dependence of UV/Visible spectra of molecules in the gas and condensed phase 2) Separation and identification of carotenoids in human macular pigment 3) Thermochemistry of coordination compounds 4) Competitive chelation of porphyrins; implications for geoporphyrin chemistry 5) Kinetics of monochloramine oxidation of Syringaldozine The UV/VIS spectrophotometer will represent a significant addition to the research and teaching instrumentation available to this RUI institution that has set the increased participation of talented black and hispanic students as one of its primary goals.
