FT-IR Spectroscopy and Computer Interfaced Instrumentation in the Chemistry Curriculum

该项目将通过将傅里叶变换红外（FT-IR）光谱学整合到六门本科化学课程中，为学生提供计算机接口仪器的实践经验。在普通化学中，该仪器将用于研究同位素取代，并将未知化合物的光谱与计算机数据库中的光谱相关联。在有机化学中的应用包括结构解释和鉴定反应产物，从天然来源分离的化合物，和现实生活中的样品（如肉桂和漱口水）。学生合成的聚合物将用傅里叶变换红外光谱进行表征。在仪器分析中，学生将在方法开发实验中记录单根头发的红外光谱，并将确定汽油酒精样品中乙醇的百分比。其他FT-IR实验包括物理化学中配体取代反应的动力学研究和生物化学中水溶液中酶-底物相互作用的动力学研究。学生获得的经验将使他们具备应用于其他计算机接口仪器的技能，并为研究生院和劳动力提供宝贵的培训。

This project will give students hands-on experience with computer-interfaced instrumentation by incorporating fourier transform infrared (FT-IR) spectroscopy into six undergraduate chemistry courses. In General Chemistry, the instrument will be used to study isotopic substitution and to correlate the spectrum of an unknown compound with those in a computerized database. Applications in Organic Chemistry include structural interpretation and identification of reaction products, compounds isolated from natural sources, and real life samples (e.g., cinnamon and mouthwash). Polymers synthesized by students will be characterized by FT-IR. In Instrumental Analysis, students will record IR spectra of single strands of hair in a methods development experiment and will determine the percentage of ethanol in gasohol samples. Other FT-IR experiments include a kinetics study of a ligand substitution reaction in Physical Chemistry and enzyme-substrate interactions in aqueous solution in Biochemistry. The experience gained by students will give them skills to apply to other computer-interfaced instruments and valuable training for graduate school and the workforce.
