The goal of this project is to incorporate Fourier-Transform Infrared (FT-IR) analysis into several chemistry courses at Sacramento City College (SCC). Currently our dispersive instrument is used for a variety of tasks. The organic students use IR as a tool for substance identification including reaction rnixture/product analysis and the investigation of components in naturaI product mixtures. Analyses performed with our current IR spectrophotometer are slow. The low student throughput and the lack of modem features limits our ability to update existing curricula. We propose to update the spectroscopy component of our curriculum and replace our dispersive IR with an FT-IR spectrophotometer. The main beneficiary of this project will be the organic chemistry courses at SCC, however, allied health chemistry students as well as second semester general chemistry students will also benefit. The incorporation of FT-IR into the organic chemistry curriculum will allow for the enhancement and modernization of existing experiments, the introduction of new methods of data analysis, and the discussion of FT-IR theory. The use of FT-IR and reflectance accessories will virtually eliminate the time constraints associated with the use of our dispersive instrument, thereby allowing for increased student access to lR spectroscopic methods. For allied health students, a more instructive and meaningful experience with IR will be possible. The introduction of FT-IR into general chemistry will provide students with a connection between acquisition of data and theoreticaI concepts presented in lecture as well as hands-on experience with a type of instrumentation which is used in industry and in the upcoming, higher level coursework students will eventually encounter.

该项目的目标是将傅里叶变换红外（FT-IR）分析纳入萨克拉门托城市学院（SCC）的几门化学课程中。目前，我们的色散仪器用于各种任务。有机学生使用红外作为物质鉴定的工具，包括反应混合物/产物分析和天然产物混合物成分的研究。用我们目前的红外分光光度计进行的分析是缓慢的。低学生吞吐量和缺乏现代化的功能限制了我们更新现有课程的能力。我们建议更新我们课程中的光谱学部分，用FT-IR分光光度计取代色散IR。这个项目的主要受益者将是SCC的有机化学课程，然而，联合健康化学学生以及第二学期的普通化学学生也将受益。将傅里叶变换红外（FT-IR）纳入有机化学课程将有助于现有实验的改进和现代化，引入新的数据分析方法，并讨论傅里叶变换红外（FT-IR）理论。使用FT-IR和反射附件将几乎消除与使用我们的色散仪器相关的时间限制，从而允许更多的学生使用lR光谱方法。对于专职卫生专业的学生来说，将有可能获得更有启发性和有意义的IR经验。将FT-IR引入普通化学将为学生提供数据获取与课堂上介绍的理论概念之间的联系，以及在工业中使用的一种仪器的实践经验，以及学生最终将遇到的更高水平的课程。
