GC/FT/IR/Raman in Undergraduate Teaching Laboratories

该项目涉及购买一台气相色谱、傅里叶变换、红外拉曼光谱仪，供本科教学实验室使用。该仪器有一个现代化的数据系统，正在连接到计算机网络，使大量的学生接触到实际的现代分离和振动光谱。接触和“动手”使用该仪器的程度从大一开始，一直到大四。该部门是非常兴奋的可能性，初步学生接触在大一化学荣誉部分，其中温室气体的光谱实验正在提出。 在有机实验室中，学生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IR和拉曼选择规则的实验。无机化学专业的学生可以常规地使用该仪器来研究他们合成的一些有机金属配合物的IR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的学生或更复杂的实验，甚至在大二的水平。然而，仔细选择实验，有效地利用仪器时间，并通过网络轻松访问数据，使该部门能够让许多学生接触到实际的，“动手”的分离和振动光谱。

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.
