Surface Reactions, Material Science, and Computer ControlledInstrumentation with Fourier Transform Infrared Spectroscopyin Undergradaute Instrumental Analysis

在使用傅里叶变换红外光谱的高级仪器分析课程中介绍了涉及材料(特别是聚合物)和表面的分析化学的实验。漫反射和光声检测用于不透明样品的分析，如聚合物纤维、煤炭、土壤和矿物。用镜面反射比和衰减全反射比说明了聚合物或金属表面上表面物种的分析表征。这些实验展示了现代光谱技术应用于复杂、不同种类系统的力量，并将学生暴露在非常实用的“现实世界”性质的问题中。还强调了计算机控制仪器的基础知识。这些实验正在使用光谱减法和归一化软件例程，以及用于分析聚合物混合物的光谱库。受赠人匹配来自非联邦来源的奖励。

Experiments involving the analytical chemistry of materials (with special emphasis on polymers) and surfaces are being introduced in the senior Instrumental Anaylsis course using Fourier transform infrared spectroscopy. Diffuse reflectance and photoacoustic detection is being used to illustrate the analysis of opaque samples such as polymer fibers, coal, soil, and minerals. The analytical characterization of surface species on polymer or metal surfaces is being illustrated using specular reflectance and attenuated total reflectance. Such experiments are illustrating the power of modern spectroscopic techniques as applied to complex, heterogeneous systems and are exposing the students to problems of a very practical "real world" nature. The basics of computer controlled instrumentation is also being stressed. The experiments are using spectral substraction and normalization software routines, as well as the spectral libraries for the analysis of polymer mixtures.
