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. *

两个学期的高级无机化学在没有实验室的情况下教授，以增强在课堂上学到的理论思想。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让学生对无机化学的进展有了一个非常有缺陷的看法。这个项目的目标是找到一种现代化的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，在秋季课程中，学生将重点学习使用新型分光光度计来探索与无机化合物相关的分子光谱学的基本原理和思想。在春季学期，该仪器将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诱导的颜色变化，以及动力学分析。这个项目使非裔美国学生受益，因为这所大学是一所历史悠久的黑人学校。无机化学实验室极大地加强了本科化学课程，因为它加强了教学能力，并为少数民族学生提供了使用现代仪器的实践经验。在这里开发的新实验可以发表在《化学教育杂志》上。*
