The Department of Chemistry will require a nitrogen laser and computer-interfaced UV/VIS spectrophotometer to improve their undergraduate education in chemistry. The first part of this project will bring computers into the physical chemistry laboratory to give students experience in using computer-interfaced instrumentation and to reduce the time required to analyze raw data. It is hoped this will increase the appeal of this course to prospective chemistry majors and reduce a major barrier to their completing a B.S. major in chemistry. The combination of computers with high-resolution plotters will also allow quantitative estimation of errors to be made much more quickly and more routinely. The computers will also be used with a molecular orbital program to interpret the absorption spectra of dyes and aromatic compounds and to teach the BASIC programming language. The new instrumentation will allow the introduction of three new experiments into the physical chemistry laboratory course as well as significant upgrading of several existing experiments. The nitrogen laser will allow for measurement of fluorescence decay times in the 1 nanosecond range. Other new experiments include "The Photochemistry of NO2" and "The Statistical Thermodynamics of Iodine Sublimation."

化学系将需要一台氮激光器和计算机接口的UV/VIS分光光度计来改善他们在化学方面的本科教育。这个项目的第一部分将把计算机带入物理化学实验室，让学生体验使用计算机接口的仪器，并减少分析原始数据所需的时间。希望这将增加这门课程对未来化学专业学生的吸引力，并减少他们完成化学学士专业的一个主要障碍。计算机与高分辨率绘图仪的结合还将使对误差的定量估计更快、更例行化。计算机还将与分子轨道程序一起使用，以解释染料和芳香族化合物的吸收光谱，并教授基本编程语言。新的仪器将允许在物理化学实验室课程中引入三个新的实验，并对几个现有的实验进行重大升级。氮激光将允许在1纳秒范围内测量荧光衰减时间。其他新的实验包括“NO2的光化学”和“碘升华的统计热力学”。
