Improvement of Chemistry Laboratories with FTIR Spectroscopy

这个项目的目的是加强实验室学习经验的课程填充化学，生物学，和专业预科专业。 在几个实验室（有机，仪器，物理，生物化学和研究）中使用所需的傅里叶变换红外光谱仪（FTIR），学生可以发现各种化学物质的分子和定量信息。 几个创新的实验，以提高学生的学习结果在氢键和物理状态和氢键强度和电负性之间的关系的发现;从旋转能和键离解能的泛音光谱测量键距离;定性和定量分析环境样品;和蛋白质和核酸二级结构的变化检查。 傅里叶变换红外光谱仪还为正在进行的确定农药在环境基质中持久性的研究项目提供了便利。 通过在连续的实验室中使用FTIR，研究生学习的学生或环境工作人员为学术，工业，私人和政府实验室的研究和测试应用做好了充分的准备。

This project is designed to enhance the laboratory learning experience in courses populated by chemistry, biology, and pre- professional majors. Using the requested Fourier Transform Infrared Spectrometer (FTIR) in several laboratories (organic, instrumental, physical, biochemistry, and research), students discover molecular and quantitative information about diverse chemical substances. Several innovative experiments to enhance student learning result in the discovery of the relationship between hydrogen bonding and physical state and hydrogen bond strength and electronegativity; measurement of bond distances from rotational energies and bond dissociation energies from overtone spectra; qualitative and quantitative analysis of environmental samples; and examination of changes in protein and nucleic acid secondary structure. The FTIR also facilitates an ongoing research project to determine pesticide persistence in environmental matrices. Through use of the FTIR in successive laboratories, students headed for graduate study or the environmental workforce are well prepared for the research and testing applications of academic, industrial, private, and governmental laboratories.
