A Fourier Transform infrared spectrometer (FT-IR) is giving the students hands-on experience with modern infrared instrumentation and current infrared sampling techniques. With the spectrometer's integral computer the students are being exposed to computer controlled instrumentation and computer analysis of data earlier in their course work. The principles introduced by exposure of students to the FT-IR are forming the basis of explanation of other instruments using transform methods or which are interfaced to computers. The spectrometer with its accessories is allowing the students to expand their analysis experience with mixtures, opaque solids, powders, and surfaces using reflectance techniques. The aqueous liquid cell is making possible the routine vibrational analysis of aqueous solutions. Current experiments in the department are being modified and new experiments are being produced for undergraduate students which are taking into account the capabilities of an FT-IR spectrometer, computer analysis of spectra and reflectance techniques for analysis. The range, sensitivity, and resolution of the instrument is also being used by students doing undergraduate research in organometallic synthesis and molecular structure. The grantee is matching the award from non-Federal sources.

傅里叶变换红外光谱仪(FT-IR)为学生提供现代红外仪器和当前红外采样技术的实践体验。有了光谱仪的集成计算机，学生们在课程作业的早期就可以接触到计算机控制的仪器和数据的计算机分析。通过让学生接触FT-IR而介绍的原理正在形成使用变换方法或与计算机接口的其他工具的解释基础。该光谱仪及其附件使学生能够利用反射技术扩展他们对混合物、不透明固体、粉末和表面的分析经验。水液室使水溶液的常规振动分析成为可能。该系目前的实验正在进行改进，并正在为本科生制作新的实验，考虑到FT-IR光谱仪、计算机光谱分析和用于分析的反射技术的能力。该仪器的量程、灵敏度和分辨率也被正在进行有机金属合成和分子结构研究的本科生使用。受赠人匹配来自非联邦来源的奖励。
