Integration of Fourier Transform Infrared Spectrophotometry Into the Chemistry Curriculum

化学系和生物系正在购买傅立叶变换红外光谱仪(FTIR)，用于这两个系的化学教学。学生学习使用计算机控制的FTIR分光光度来阐明有机结构以及数据处理和分析。FTIR的高灵敏度和分析速度使其能够用于比以前的仪器更多种类的实验。计算机搜索能力使学生了解红外分析中固有的识别过程，并展示计算机数据库与仪器接口的实用性。在有机化学实验室，学生们使用该仪器识别2，6-二甲基硝基苯多步合成利多卡因过程中涉及的关键化合物。在工具分析课程中，学生学习FTIR的理论和实践两个方面。在物理化学课程中，对氯化氢和氯化氢的红外振动光谱的转动精细结构进行了实验研究。此外，一门面向非专业学生的化学入门通识教育课程为学生提供了FTIR分析的经验，包括阿司匹林的提纯等步骤。

The Departments of Chemistry and Biology are purchasing a Fourier Transform infrared spectrometer (FTIR) for use in chemically oriented instruction in both departments. Students learn the use of computer controlled FTIR spectrophotometry for the elucidation of organic structures as well as data manipulation and analysis. The high sensitivity and analysis speed of the FTIR allow use for a greater variety of experiments than was possible with prior instruments. The computer search capabilities provide students with an understanding of the identification process inherent in infrared analysis and demonstrate the usefulness of computer database interfacing to instruments. In the organic chemistry laboratory, students use the instrument to identify the key chemical compounds involved in the multi-step synthesis of lidocaine from 2,6-dimethylnitrobenzene. In the instrumental analysis course, students study both the theoretical and practical aspects of FTIR. In the physical chemistry course, an experiment is performed to study the rotational fine structure of the infrared vibrational spectra of hydrogen chloride and deuterium chloride. In addition, a general education course in introductory chemistry for non-majors provides students with experiences in FTIR analysis involving such procedures as the purification of aspirin.
