9351495 Jasinski A Fourier Transform Infrared Spectrometer (FTIR) is serving as a cornerstone of our new laboratory teaching effort. The instrument is being used in laboratories at all levels. Beginning with demonstration in a project-oriented introductory chemistry lab, the instrument is being used in increasingly sophisticated ways in higher level courses. Introduction of FTIR into the introductory organic laboratory is enhancing the ability of students to accurately analyze the small amounts of compounds that result from microscale experiments. In addition, students are being introduced to a wider variety of sampling techniques, including diffuse reflectance. Judicious choice of detectors (DTGS or MCT) allows for more sensitivity to low light throughput at a faster scan rate than dispersive IR spectrometers. FTIR techniques are enhancing our capabilities in the instrumental course as well as the polymers, pharmaceutical and medicinal applications in the industrial chemistry laboratory and in undergraduate research. Students are being introduced to modern spectral manipulation and database searching techniques as well as essential parameters of FTIR spectroscopy including signal averaging, repetitive scanning, resolution comparison and standards collections. ***

9351495亚辛斯基傅里叶变换红外光谱仪是我们新的实验教学工作的基石。该仪器正在各级实验室中使用。从一个以项目为导向的入门化学实验室的演示开始，该仪器正以越来越复杂的方式在更高级别的课程中使用。将傅里叶变换红外光谱引入有机实验室，提高了学生从微型实验中准确分析少量化合物的能力。此外，还向学生介绍了更多种类的采样技术，包括漫反射。明智地选择探测器(DTGS或MCT)允许以比色散红外光谱仪更快的扫描速度对低光通量更敏感。FTIR技术正在增强我们在仪器课程以及在工业化学实验室和本科生研究中的聚合物、制药和医药应用方面的能力。向学生介绍现代光谱操作和数据库搜索技术以及FTIR光谱的基本参数，包括信号平均、重复扫描、分辨率比较和标准收集。***
