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.

该项目旨在增强化学、生物学和专业预科课程中的实验室学习体验。 在多个实验室（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)，学生可以发现有关不同化学物质的分子和定量信息。 几项促进学生学习的创新实验发现了氢键与物理状态以及氢键强度和电负性之间的关系；根据旋转能测量键距，并根据泛音谱测量键解离能；环境样品的定性和定量分析；以及检查蛋白质和核酸二级结构的变化。 FTIR 还促进了一项正在进行的研究项目，以确定环境基质中农药的持久性。 通过在连续的实验室中使用 FTIR，即将攻读研究生的学生或环境工作者可以为学术、工业、私人和政府实验室的研究和测试应用做好充分准备。
