Modern UV/Visible Spectroscopy for Improvement of Freshman- Sophomore Chemistry Instruction

通过购买新的带计算机接口的二极管阵列紫外/可见光(UV/VIS)分光光度计，该项目将UV/VIS光谱的概念、实践和专业用途整合到两年制课程中。在普通化学课程中，该仪器被用作学习定量分析和鉴定的基本原理的工具，并为独立实验室项目提供了更多的选择。有机化学水平的学生正在利用他们的有机实验室项目中增加的仪器分析组件的选择。该项目还通过展示现代仪器在动手解决问题的环境中的使用，向非理科学生介绍了现代仪器。在所有层面上，正在设计使用UV/VIS分光光度计的实验，以清楚地说明仪器的方法、应用和限制。*

Through the purchase of a new diode-array ultraviolet/visible (UV/VIS) spectrophotometer with computer interface, this project is integrating the concepts, practice, and specialized uses of UV/VIS spectroscopy into the 2-year curriculum. In the general chemistry course, the instrument is being used as a tool for learning the fundamentals of quantitative analysis and identification and is allowing for more choices for independent laboratory projects. Students at the organic chemistry level are taking advantage of the increased options for the instrumental analysis components of their organic laboratory projects. The project is also introducing non-science-students to modern instrumentation by demonstrating its uses in a hands-on, problem-solving context. At all levels, experiments are being devised that use the UV/VIS spectrophotometer to clearly illustrate instrumental methods, applications, and limitations. *
