UV-Visible Spectrophotometer for the Undergraduate InorganicChemistry Laboratory

两个学期的高级无机化学课程都是在没有实验室的情况下进行的，以增强课堂上所学到的理论思想。由于无机化学是一门建立在实验基础上的学科，以前在没有实验室的情况下教授无机化学的做法，使学生对无机化学的发展过程产生了非常错误的看法。该项目的目标是找到一种现代紫外可见分光光度计，它将与其他仪器一起使用，将无机化学实验室纳入课程。新实验室提供两门高级无机化学课程，涵盖无机化学的所有基本领域。因此，在秋季，学生们专注于使用新的分光光度计来探索分子光谱的基本原理和思想，因为它们与无机化合物有关。在春季学期，该仪器用于研究配位化合物的化学，混合物的分析，固体和溶液中光和热引起的颜色变化，以及动力学分析。这个项目使非裔美国学生受益，因为这所大学历来是一所黑人大学。无机化学实验室极大地加强了本科化学课程，因为它增强了教学能力，并为少数民族学生提供了一个实践使用现代仪器的途径。这里开发的新实验可以发表在《化学教育杂志》上。＊

Two semesters of advanced inorganic chemistry have been taught without a laboratory component to augment the theoretical ideas learned in the classroom. Since inorganic chemistry is a discipline founded on experimentation, the previous practice of teaching it without a laboratory gives students a very flawed view of how inorganic chemistry progresses. The goal of this project is to find a modern ultraviolet visible spectrophotometer that will be used with other instruments to incorporate an inorganic chemistry laboratory into the curriculum. The new laboratory serves two upper-level inorganic chemistry courses, which cover all essential areas of inorganic chemistry. Consequently, during the fall, students focus on the use of the new spectrophotometer in exploring basic principles and ideas of molecular spectroscopy as they relate to inorganic compounds. In the spring semester, the instrument is used in studying the chemistry of coordination compounds, analysis of mixtures, light- and heat-induced color changes in the solid state and in solution, and kinetic analyses. This project benefits African-American students because the university is a historically black institution. The inorganic chemistry laboratory greatly enhances the undergraduate chemistry curriculum because it reinforces the teaching capabilities and provides an avenue for minority students to get hands-on experience in the use of a modern instrument. New experiments developed here can be published in the Journal of Chemical Education. *
