Improvement of Undergraduate Science Instruction with FTIR Spectroscopy

该项目将通过为学生提供微观尺度光谱分析的实践经验来加强本科理科课程。该计划的重点是获得一台具有计算机数据处理和图书馆搜索功能的傅里叶变换红外光谱仪。仪器的主要用途将是在有机化学，仪器分析和物理化学实验课程。学生将通过以下方式获得重要经验：a)将理论原理应用于当代问题，包括地下水、土壤和空气污染监测，以及溶剂和食品包装（聚合物和添加剂）等商业商品的分析；B)样品制备技术的学习；C)利用计算机提高灵敏度，通过多次扫描、光谱叠加和定量方法分析数据；D)与库数据库进行光谱搜索和匹配；e)观察FTIR光谱仪的内部硬件配置。这个项目很有意义，因为学生需要体验如何用现代仪器在微观水平上分析和检测化合物。此外，这些经验将为更好地理解其他现代光谱分析方法（如FT-NMR）提供基础。

9450945 Bezoari The project will enhance undergraduate science courses by providing students with hands-on experiences in spectroscopic analysis on the microscale level. The plan centers on the acquisition of a Fourier Transform Infrared (FTIR) spectrometer with computer data handling and library search capabilities. The primary use of the instrument will be in the Organic Chemistry, Instrumental Analysis, and Physical Chemistry laboratory courses. Students will gain important experiences by: a) applying theoretical principles to contemporary problems Including ground- water, soil, and air pollution monitoring, and analysis of commercial goods such as solvents and food-packaging (polymers and additives); b) learning techniques of sample preparation; c) using the computer to enhance sensitivity and analyze data with multiple scans, spectral overlay, and quantitative methods; d) carrying out searching and matching of spectra with the library data bank; and e) seeing the internal hardware arrangements used in the FTIR spectrometer. The project is meaningful because students need to experience how compounds are analyzed and detected on the microscale level with modern instrumentation. Furthermore, these experiences will provide the foundation to promote a better understanding of other modern spectroscopic methods of analysis (e.g., FT-NMR).
