This project involves the purchase of a gas chromatographic, Fourier-transform, infrared Raman spectrometer for use in the undergraduate teaching laboratories. The instrument has a modern data system which is being connected to the computer network, allowing exposure of large numbers of students to practical modern separations and vibrational spectroscopy. The degree of exposure and `hands-on` use of the instrument begins at the freshman level and increases to the senior level. The department is very excited about the possibility of initial student contact in the freshman chemistry honors section, for which a spectroscopic experiment on greenhouse gases is being proposed. In the organic laboratory, students separate mixtures and identify compounds that they have synthesized. Students in the physical chemistry laboratory carry out experiments on hydrogen bonding that require Raman capabilities and experiments involving IR and Raman selection rules. The inorganic chemistry students can routinely use the instrument to study the IR and Raman spectra of a number of organometallic complexes that they have synthesized. In the analytical laboratories, students extract a simulated urine sample and carry out a GC/IR drug screen. Existing university IR spectrometers cannot handle the large numbers of students or the more sophisticated experiments proposed even at the sophomore level. However, careful choice of experiments, efficient use of instrument time, and easy data access through the network enables the department to expose many students to practical, `hands-on` separations and vibrational spectroscopy.

该项目涉及购买一台用于本科教学实验室的气相色谱、傅里叶变换红外拉曼光谱仪。该仪器有一个连接到计算机网络的现代数据系统，使大量学生能够接触到实用的现代分离和振动光谱。接触和动手使用该仪器的程度从一年级开始，并增加到高级水平。该系对一年级化学荣誉部分有可能与学生进行初步接触感到非常兴奋，为此提出了一个关于温室气体的光谱实验。在有机实验室里，学生们分离混合物，并识别他们合成的化合物。物理化学实验室的学生进行需要拉曼能力的氢键实验，以及涉及红外和拉曼选择规则的实验。无机化学学生可以常规使用该仪器研究他们合成的一些有机金属络合物的红外光谱和拉曼光谱。在分析实验室，学生提取模拟尿样，并进行GC/IR药物筛选。现有的大学红外光谱仪无法处理大量学生或更复杂的实验，即使是在大二的水平上也是如此。然而，精心选择实验，有效利用仪器时间，以及通过网络轻松访问数据，使该系使许多学生接触到实际的、动手操作的分离和振动光谱学。
